string.js - Extra JavaScript string methods.

•    Javascript

---

string.js, or simply S is a lightweight (< 5 kb minified and gzipped) JavaScript library for the browser or for Node.js that provides extra String methods. Originally, it modified the String prototype. But I quickly learned that in JavaScript, this is considered poor practice.Personally, I prefer the cleanliness of the way code looks when it appears to be native methods. i.e. when you modify native JavaScript prototypes. However, if any app dependency required string.js, then the app's string prototype would be modified in every module. This could be troublesome. So I settled on creating a wrapper a la jQuery style. For those of you prototype hatin' fools, there is the method extendPrototype().

string_score - JavaScript string ranking 0 for no match upto 1 for perfect

•    Javascript

---

Simply include one of the string score JavaScript files and call the .score() method on any string. ** IE 7 fails (stop running this script message) with 4000 iterations of the benchmark test. All other browsers tested survived this test, and in fact survive a larger number of iterations. The benchmark that is causing IE to choke is: 4000 iterations of 446 character string scoring a 70 character match.

javascript-obfuscator - A powerful obfuscator for JavaScript and Node.js

•    TypeScript

---

JavaScript obfuscator is a powerful free obfuscator for JavaScript with a wide number of features which provides protection for your source code. It is not recommended to obfuscate vendor scripts and polyfills, since the obfuscated code is 15-80% slower (depends on options) and the files are significantly larger.

magic-string - Manipulate strings like a wizard

•    Javascript

---

Suppose you have some source code. You want to make some light modifications to it - replacing a few characters here and there, wrapping it with a header and footer, etc - and ideally you'd like to generate a source map at the end of it. You've thought about using something like recast (which allows you to generate an AST from some JavaScript, manipulate it, and reprint it with a sourcemap without losing your comments and formatting), but it seems like overkill for your needs (or maybe the source code isn't JavaScript).Your requirements are, frankly, rather niche. But they're requirements that I also have, and for which I made magic-string. It's a small, fast utility for manipulating strings and generating sourcemaps.

expect-jsx - ✅ toEqualJSX for expect assertion library

•    Javascript

---

Note from maintainers Since Jest supports snapshot testing, we recommend you to use that instead of expect-jsx. expect-jsx is no more compatible with recent Jest versions (22), it can be made compatible so feel free to open a PR if so.
