海外TECH	DEV Community	The Difference between TypeScript and Javascript	https://dev.to/smpnjn/the-difference-between-typescript-and-javascript-3gem	The Difference between TypeScript and JavascriptIf you re new to web development or just Javascript development you may find yourself wondering what is the difference between TypeScript and Javascript In this guide I ll explain exactly what TypeScript is and why it s different from Javascript If you re looking to start your own TypeScript project I wrote a guide here on setting up your first TypeScript project How is TypeScript different from JavaScript When the web started out JavaScript was a scripting language that allowed us to add interactivity to website Javascript was famously written in days so as you might expect it didn t have all the features we have today As time went on Javascript s importance only grew Frameworks evolved like jQuery Mootools and then React Vue and Svelte Then Javascript became a backend language too with Node JS As it grew in importance all the quirks peculiarities and missing features of Javascript became more noticeable For programmers coming from strongly typed languages one of these missing features was a type system What are types In Javascript type is dynamic based on how you write your code This is different from some other languages where you have to mention explicitly the type of everything In Javascript it s easier let x Type is Numberlet y string Type is Stringlet z Type is objectThis is actually a great feature It makes Javascript easy entry for developers who want to create something fast It has drawbacks though The major one is that if you work with multiple teams complex systems where enforcing types is important or just face a lot of issues because of TypeErrors it can become a hinderance rather than a net positive for your applications TypeScript tries to solve this issue The only thing it really does is adds types to Javascript and it means you have to define types of your code more often Using our previous example we could define the types of our variables like this let x number Type is Numberlet y string string Type is Stringlet z object Type is objectIt doesn t end there though For example writing a simple function in Javascript may look like this let myFunction x y gt return x y Whereas TypeScript lets us define types for all arguments and the return value of the function let myFunction x number y number number gt return x y Learning TypeScript is therefore a little different than Javascript If you re interested you can learn more about types in TypeScript here Features of TypeScriptIt is strongly typed as mentioned we have to define types in TypeScript whereas we do not in Javascript It still works like Javascript all the functions methods and everything you re used to still exist in TypeScript It just has types added on too It has a compile step and compiles to Javascript TypeScript can t be run on a browser Instead you write your code with types and then they are compiled to vanilla Javascript without types That means you know your code is typed properly before you compile it after which it s just plain Javascript that can run on the web Why use TypeScript The main reason people and organisations use TypeScript is because it s type safe you can strongly type all of your code and ultimately this leads to less bugs and issues further down the line When the return type of a function or the input type of a variable is defined developers can t accidentally write true instead of true Is TypeScript better than Javascript TypeScript is not better than Javascript it just gives you the ability to define your types in your code Sometimes you may not need that and the main disadvantage to Typescript is the compile time In Javascript code is ready to go as soon as you write it but in TypeScript it requires you to compile it down to Javascript In the future types may come to Javascript in one form or another which will potentially remove this compile step For now though this takes time and may not be your preferred method of writing code if you don t have to This is the main benefit of sticking with Javascript but there are others for small apps strongly typing your code may provide no added benefit as well Therefore don t feel like you need to use TypeScript use whatever makes sense for your product or organisation ConclusionIf you are new to TypeScript I write quite a bit about it here It s a great language and provides a lot of safety with regards to types that Javascript does not TypeScript is not better than Javascript but it may be more familiar to you if you have come from a strongly typed background It may also be the preferred option if you work on large products or with many teams It s important you select the toolset that is applicable to your situation though but there is no harm in learning TypeScript given its growing popularity If you ve enjoyed this you can catch me on twitter here	2022-10-16 14:41:45
海外TECH	Engadget	Hitting the Books: The women who made ENIAC more than a weapon	https://www.engadget.com/hitting-the-books-proving-grounds-kathy-kleiman-grand-central-publishing-143001879.html?src=rss	Hitting the Books The women who made ENIAC more than a weaponAfter Mary Sears and her team had revolutionized the field of oceanography but before Katherine G Johnson Dorothy Vaughan and Mary Jackson helped put John Glenn into orbit a cadre of women programmers working for the US government faced an impossible task train ENIAC the world s first modern computer to do more than quickly calculate artillery trajectories Though successful ーand without the aid of a guide or manual no less ーtheir names and deeds were lost to the annals of history until author Kathy Kleiman through a Herculean research effort of her own brought their stories to light in Proving Ground The Untold Story of the Six Women Who Programmed the World s First Modern Computer Grand Central PublishingExcerpted from the book Proving Ground The Untold Story of the Six Women Who Programmed the World s First Modern Computer by Kathy Kleiman Copyright by First Byte Productions LLC Reprinted with permission of Grand Central Publishing All rights reserved Demonstration Day February The Moore School stood ready as people began to arrive by train and trolley John and Pres as well as the engineers and deans and professors of the university wore their best suits and Army officers were in dress uniform with their medals gleaming The six women wore their best professional skirt suits and dresses Kay and Fran manned the front door of the Moore School As the scientists and technologists arrived some from as far as Boston the two women welcomed them warmly They asked everyone to hang up their heavy winter coats on the portable coat racks that Moore School staff had left nearby Then they directed them down the hall and around the corner to the ENIAC room Just before a m Fran and Kay ran back to be in the ENIAC room when the demonstration began As they slid into the back of the room everything was at the ready At the front of the great ENIAC U there was space for some speakers a few rows of chairs and plenty of standing room for invited guests and ENIAC team members Across the room Marlyn Betty and Jean stood in the back and the women smiled to each other Their big moment was about to begin Ruth stayed outside pointing late arrivals in the right direction The room was packed and was filled with an air of anticipation and wonder as people saw ENIAC for the first time Demonstration Day started with a few introductions Major General Barnes started with the BRL officers and Moore School deans and then presented John and Pres as the co inventors Then Arthur came to the front of the room and introduced himself as the master of ceremonies for the ENIAC events He would run five programs all using the remote control box he held in his hand The first program was an addition Arthur hit one of the but tons and the ENIAC whirled to life Then he ran a multiplication His expert audience knew that ENIAC was calculating it many times faster than any other machine in the world Then he ran the table of squares and cubes and then sines and cosines So far Demonstration Day was the same as the one two weeks earlier and for this sophisticated audience the presentation was pretty boring But Arthur was just getting started and the drama was about to begin He told them that now he would run a ballistics trajectory three times on ENIAC He pushed the button and ran it once The trajectory “ran beautifully Betty remembered Then Arthur ran it again a version of the trajectory without the punched cards printing and it ran much faster Punched cards actually slowed things down a little bit Then Arthur pointed everyone to the grids of tiny lights at the top of the accumulators and urged his attendees to look closely at them in the moments to come He nodded to Pres who stood against the wall and suddenly Pres turned off the lights In the black room only a few small status lights were lit on the units of ENIAC Everything else was in darkness With a click of the button Arthur brought the ENIAC to life For a dazzling twenty seconds the ENIAC lit up Those watching the accumulators closely saw the tiny lights twinkle as they moved in a flash first going up as the missile ascended to the sky and then going down as it sped back to earth the lights forever changing and twinkling Those twenty seconds seemed at once an eternity and instantaneous Then the ENIAC finished and darkness filled the room again Arthur and Pres waited a moment and then Pres turned on the lights and Arthur announced dramatically that ENIAC had just completed a trajectory faster than it would take a missile to leave the muzzle of artillery and hit its target “Everybody gasped Less than twenty seconds This audience of scientists technologists engineers and mathematicians knew how many hours it took to calculate a differential calculus equation by hand They knew that ENIAC had calculated the work of a week in fewer than two dozen seconds They knew the world had changed Climax complete everyone in the room was beaming The Army officers knew their risk had paid off The ENIAC engineers knew their hardware was a success The Moore School deans knew they no longer had to be worried about being embarrassed And the ENIAC Programmers knew that their trajectory had worked perfectly Years of work effort ingenuity and creativity had come together in twenty seconds of pure innovation Some would later call this moment the birth of the “Electronic Computing Revolution Others would soon call it the birth of the Information Age After those precious twenty seconds no one would give a second look to the great Mark I electromechanical computer or the differential analyzer After Demonstration Day the country was on a clear path to general purpose programmable all electronic computing There was no other direction There was no other future John Pres Herman and some of the engineers fielded questions from the guests and then the formal session finished But no one wanted to leave Attendees surrounded John and Pres Arthur and Harold The women circulated They had taken turns running punched cards through the tabulator and had stacks of trajectory printouts to share They divided up the sheets and moved around the room to hand them out Attendees were happy to receive a trajectory a souvenir of the great moment they had just witnessed But no attendee congratulated the women Because no guest knew what they had done In the midst of the announcements and the introductions of Army officers Moore School deans and ENIAC inventors the Programmers had been left out “None of us girls were ever introduced as any part of it that day Kay noted later Since no one had thought to name the six young women who programmed the ballistics trajectory the audience did not know of their work thousands of hours spent learning the units of ENIAC studying its “direct programming method breaking down the ballistics trajectory into discrete steps writing the detailed pedaling sheets for the trajectory program setting up their program on ENIAC and learning ENIAC “down to a vacuum tube Later Jean said they “did receive a lot of compliments from the ENIAC team but at that moment they were unknown to the guests in the room And at that moment it did not matter They cared about the success of ENIAC and their team and they knew they had played a role a critical role in the success of the day This was a day that would go down in history and they had been there and played an invaluable part	2022-10-16 14:30:01
