Vanilla JS helpers

This is a collection of simple, no dependency, vanilla JS snippets with the aim of making it easier to work with vanilla JS.

All helpers are written in TypeScript and converted into various JS versions suiting your use case:

.js: ES 5+ syntax.
.mjs: ES 2020 syntax
.cjs: ES 2017 syntax + CommonJS require imports
.d.ts: TypeScript description files

BROWSER SPECIFIC HELPERS

These helpers a JS platform agnostic, for browser specific helpers check out: vanillajs-browser-helpers

ES version support

All methods are using latest techniques and generally no efforts have been made to accommodate older browsers which do not support certain features. Polyfills should be used to fill the gap. This is intentional as the need for polyfills are ever diminishing, with modern browsers (and Node environments) getting updated all the time the vast majority of the methods will be supported at one point. Also, with compilers like Babel, polyfills can be included automatically in the build process, making it simple to ensure full support. Therefore it is more future proof and clutter free to leave fallbacks and polyfills out of the methods and just focus on core functionality.

Only in few edge cases where a polyfill might be tricky to implement correctly for a given functionality, fallback functionality will be incorporated.

Note
You will have to add these snippets as part of your transpilation if you wish to have enable auto detection of polyfills.
