Benefits:

• The ability to use individual functions from the library and bundle exactly what you need (very useful for Palindrom for it only needs applyPatch. E.g (import { applyPatch } from 'fast-json-patch').
• The ability to use require and use external libs.
• Tremendous ease when modifying code.
• No more redundant review comments for same issues in .js and .ts files.
• Much cleaner repo.
• Much leaner NPM package.
• Faster Travis config (use CLI instead of xvfb).

Modifications:

• Migrate to Webpack
• Remove compiled files from repo (npm install compiles automatically).
• Remove deprecated apply.
• Use CommonJS includes.
• Use equals Node module.
• Use Array.isArray, even IE supports it now.
• Remove all duplicated code.
• Add postinstall command to be called by npm install to compile TS code.
• Update README accordingly.
• Update CONTRIBUTING accordingly.
• Remove dist folder in favour of https://unpkg.com/.

Can we delete the generated .js and .d.ts files from git then? It would make reviewing and rebasing PRs much easier, and if you want a CDN, use https://unpkg.com/, not GitHub.

@felixfbecker even better.

I just realized that bower used files in dist.

I suggest we remove bower, to get rid of all deperecated stuff for good. Main use case is Palindrom and Palindrom uses NPM. And Palindrom is bundled.
