JSON vs. JavaScript vs. PlayCode vs. Underscore.js Comparison Chart

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language. JSON is built on two structures: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another.

The #1 JavaScript playground and sandbox to write, run and repl it. JavaScript playground is perfect for learning and prototyping javascript sandboxes. Fast and easy to use. Start a JavaScript playground project using ready-to-use templates. JavaScript is one of the most popular languages for web development. It is needed in order to make web pages alive. Today JavaScript can be run not only in the browser but also on the server. Learning, practicing and prototyping is much easier right in the javascript playground because the browser is designed to run javascript. This is the perfect coding IDE. In turn, PlayCode tries to use all the browser features to ensure maximum, comfortable run javascript sandbox. Read, evaluate, print, and loop, a simple pre-configured coding environment that quickly shows the JavaScript execution result. So, you just open PlayCode without installing anything, write code, and JavaScript playground runs your code instantly and shows the result.
