My Svelte Journey Beginner to beginner Introduction to SvelteThe goal for this tutorial is to share my learning experience with Svelte also this is my first post in this platform roast me but be nice In November i decided to change my career and start learn to code First i was decided to prepare the exams for CCNA but then i realize that i wanted to learn web development so i started with the basics HTML CSS JavaScript and so many tools that are needed for the job After this first months it s time for the JS frameworks I decided to start with Svelte because i think it s gonna be implemented in vaste scale in the next years and so many people are talking about it right now One of this person is Mike from htmleverything probably you know him from the podcast HTML All The Things Mike is very enthusiastic about Svelte and I have to confess that I have chosen this framework following his words This post it s mostly a follow up of Mike s course so all the credits goes to him for me this is just another way to keep learning by writing and teaching others For my first post i will cover just the setup and first step more weekly updates will follow my study Svelte it s simple to use and lets us create and build apps very fast Svelte is not a library or a framework it is a compiler This means that your code is not shipped in combination with packages to a browser but it gets compiled to something else this something is shipped to the browser Because all code gets compiled the total size decreases but the performance increases Besides it allows you to break away from writing everything inside a JavaScript function and have its optimized format The Setup step by stepThe only tool required it s Node js installed in your machine and your code editor of choicheSetting up the project directory using Vite npm init vite latestIn the Svelte project npm install and npm run dev After that we will stop the server with control cNext thing installing Tailwindcss npx svelte add latest tailwindcss This will add some dependencies to our project folderAgain we will npm i and after that npm run dev to restart the serverImporting DaisyUI component library with npm i daisyui and we will paste in the plugins of the tailwind config cjs file require daisyui and saveDelete all the CSS HTML and Scripts already present in the file and the folder lib That s it to set up the project let s now dive in the components format and how to use it ComponentsSvelte it s a single file components arquitecture Script Html Style lt script gt JavaScript goes here lt script gt HTML goes here lt style gt styles goes here lt style gt The script block contains the JavaScript that we are gonna use tu run a component instance All the variables declared or imported are visible and linkable to the markup section The code we write in the components it can be shared between multiple instances To made reactive statment to access their value we prefix with a let count doubled count Anytime the value of count change the doubledvalue change as well the dollar sign make recative the component That s it for my first post about Svelte and my first blog post ever I will try to keep this as an opportunity to learn and write constantly every week or so depending on my progress on this framework Next week i will write about Conditional Rendering |

Can You Refactor JavaScript Safely Without Test Coverage? |
https://dev.to/p42/can-you-refactor-javascript-safely-without-test-coverage-2hbo

Can You Refactor JavaScript Safely Without Test Coverage The conventional wisdom is that you should have good test coverage before refactoring your code Making mistakes during refactoring will introduce defects in the software if they are not caught during testing Such regression defects can annoy users break the software and even lead to customers abandoning the product The need for automated testing is especially high for JavaScript In a dynamic language with functional constructs like JavaScript it is harder to detect breakages statically Additionally JavaScript has many language details and quirks that are not well known or easy to remember In practice however there is a chance that you will encounter situations where you need to work in untested or insufficiently tested legacy code Often this is precisely the kind of code that would benefit from refactoring to make it easier to understand and extend But to test it we need to make it testable which involves refactoring How do we resolve this problem If we take a step back the underlying question that automated testing helps us answer is a question of confidence and risk How confident am I that my refactoring has not changed the program behavior Tests help us answer the question but there is a chance that refactoring introduces bugs when there are gaps in test coverage Therefore the answer to the question is a matter of degree even with tests Another approach is taking a sequence of small steps If we are confident that each step is correct the final result is correct since no step changes the program behavior Ideally taking small low risk steps is combined with excellent test coverage leading to high confidence However significant changes a more complex programming language like JavaScript and complex legacy codebases lead to a high risk that individual steps introduce defects In particular refactorings that span module or service boundaries large scale renames where not every symbol occurrence might get picked up or extensive manual changes tend to be error prone But for single functions classes or modules it can be possible to chain together sequences of automated refactorings to achieve a more extensive refactoring However most refactoring tools ensure that the refactoring mechanics are correctly executed but they do not tell you about the impact on your code I wanted a refactoring tool with built in knowledge of many hard to remember JavaScript details that can analyze the relevant code to evaluate the safety of a refactoring With this in mind I created the P JavaScript Assistant for Visual Studio Code When possible P evaluates the refactoring impact on the logic and the flow of your code excluding performance and informs you if it is safe or if specific details need checking Here is an example of how P indicates the safety of small refactoring steps With automatic refactoring tools such as P that combine static analysis of the relevant source code with extensive knowledge of the programming language it is possible to refactor code more safely In combination with automated testing and type checking tools like TypeScript this makes it possible to refactor with high confidence even in a dynamic language like JavaScript Happy Refactoring |

Grocery chain Tesco suffers two-day outage following hack |

Grocery chain Tesco suffers two day outage following hackBritish grocery shoppers have had more than a few headaches this weekend According to The Guardian the grocery chain Tesco has grappled with a roughly two day outage as of this writing preventing customers from placing or modifying orders through either the company s website or its mobile app The company pinned the incident on hacks affecting searches although it didn t say much beyond noting the intruders tried to quot interfere with our systems quot The company didn t have an estimated time frame for a fix and didn t identify the potential culprits However it said there was quot no reason to believe quot the cyberattack affected customer data This isn t the first time Tesco has suffered hacks A breach led it to disable accounts after intruders shared more than users login details In an attack on Tesco s banking lost about £ million worth million today Whoever was responsible the incident further highlights the vulnerability of food supply chains to cyberattacks Meat supplier JBS was one of the most prominent victims after it fell prey to ransomware but grocery stores themselves are also at risk of disruptions that could limit deliveries and otherwise stop meals from reaching your table |
