JSON: All You Need to Know |
https://dev.to/aravsanj/json-all-you-need-to-know-3fl6

JSON All You Need to KnowJSON stands for JavaScript Object Notation It is a data interchange format used to communicate between the server and the client JSON is not a language but a syntax The name JavaScript Object Notation came from its deliberate similary to JavaScript objects However JSON is made keeping in mind data types like objects dictionaries arrays lists from C family of programming languages The main features of JSON include Being lightweightIs text basedAnd language independent Why JSON JSON has two structures Collection of key value pairsAn ordered listThese are structures heavily inspired by JavaScript objects and arrays In fact you could take JSON objects and JSON arrays paste it in a JavaScript file and get valid JavaScript At the same time similar data types exist in multitude of backend languages like Python PHP and Nodejs This makes JSON very easy to parse Remember JSON is a string in the end and need to be parsed to an appropriate data type for programming languages to process This is in contrast to XML the predecessor of JSON XML is also used to communicate between server and client But JSON can be parsed directly in to a JavaScript object or array which is ready for use XML is much harder to parse as it is syntactically different Example of XML lt presidents gt lt president gt lt firstName gt George lt firstName gt lt lastName gt Bush lt lastName gt lt president gt lt president gt lt firstName gt Barack lt firstName gt lt lastName gt Obama lt lastName gt lt president gt lt president gt lt firstName gt Donald lt firstName gt lt lastName gt Trump lt lastName gt lt president gt lt presidents gt Example of JSON presidents firstName George lastName Bush firstName Barack lastName Obama firstName Donald lastName Trump From the above examples you can take home three points JSON is significantly smaller and easier to read amp writeA JavaScript developer don t need to be worried about learning extra syntaxJSON can hold array of data unlike XML How to write JSON We already saw a glimpse of how JSON looks like If you want to be a serious developer you must know how to write JSON We write JSON in json file and its values must be one of the following data types stringnumberobjectarraybooleannullRemember all these are accepted data types for values in JSON JSON itself is fundamentally written in two structures discussed earlier But you can still write any of these data types in a json file and it is perfectly valid JSON that can be parsed JSON written in key value pairs name John age contact email john email com phone hobbies reading gardening gaming isLoggedIn true employment null JSON written as an array of data john contact email john email com phone reading gardening gaming true null Writing JSON shouldn t be hard if you know JavaScript But it will take sometime before you get used to the right way of nesting data for your particular use case Parsing JSONJSON is a string of data and needs to be parsed before using In the frontend JavaScript has an object called JSON that contains methods for parsing and converting to JSON data To parse a JSON data we use JSON parse const obj JSON parse json The return value of JSON parse depends on the JSON string It can be a string number object array boolean or null Mostly you will be dealing with an object or an array Here is an example of how JSON parse works JSON parse JSON parse true trueJSON parse string string JSON parse false false JSON parse null nullJSON parse accepts a second value called reviver The reviver is a function that can be used to transform the parsed value of JSON before being returned const number JSON parse key value gt value console log number Notice how I passed two parameters to the reviver function This is because the data is parsed into key value pairs For the backend parsing JSON totally depends on the language of your choice In python there is a module called json which you can import In nodejs you get access to the same JSON object Converting to JSONTo communicate we also need to convert data back to JSON string The same JSON object can used in the frontend again Since JavaScript and JSON has pretty much the same syntax all what is remaining is to convert it to a string For that we use JSON stringify method The JSON stringify method converts a JavaScript object or value to a JSON string JSON stringify JSON stringify true true JSON stringify string string JSON stringify false false JSON stringify null null null Just like JSON parse method JSON stringify also accepts a second parameter called replacer It can be used to alter the behavior of stringification process const json JSON stringify key value gt value console log json Here too I have passed two parameters The stringify method even accepts a third parameter meant for spacing const spaced JSON stringify a b null t consol log spaced a b The t is the tab character The string has added a tab space infront of each key value pair This is just for improving readability Again for the backend converting to JSON totally depends on the language of your choice Python has a module called json In nodejs you get access to same JSON object Practicing JSONTo conclude I would like to leave you with two resources that can help you practice JSON JSON Placeholder has fake api endpoints with JSON datajson server can run a local json serverThat s about it Thanks for reading |

Sony and TSMC may team up to tackle global chip shortagesGlobal chip shortages may soon create some unexpected allies in Japan As Reutersreports Nikkeisources claim Sony and TSMC are quot considering quot the joint creation of a semiconductor factory in Japan s western Kumamoto Prefecture TSMC would have majority control according to the insiders but the plant would operate on Sony land near that company s image sensor factory The Japanese government would reportedly cover up to half of the billion investment The plant would provide chips for cameras cars and other purposes Accordingly car parts giant Denso is supposedly interested in the project If the project moves forward the factory would be up and running by Sony and TSMC have declined to comment although TSMC previously said it was quot actively reviewing quot plans for an effort like this A joint plant wouldn t be surprising Some analysts expect the worldwide chip shortage to last until and that s assuming demand doesn t grow quicker than predicted This would help Sony TSMC and the larger Japanese tech industry bounce back from the shortage not to mention add greater stability It could also serve as a hedge ーJapan Sony and TSMC wouldn t have to worry about China US tensions threatening production in Taiwan The factory might be ready at just the right time Highly connected and semi autonomous cars should be more commonplace by and it s no secret that cameras play a crucial role even in budget smartphones A new plant could be crucial to keeping these technologies on track |
