Buffers events from a stream until you are ready to handle them.
The Node.js `util.deprecate()` function with browser support
deterministic JSON.stringify() with custom sorting to get deterministic hashes from stringified results, with no public domain dependencies
type-check allows you to check the types of JavaScript values at runtime with a Haskell like type syntax.
process.nextTick but always with args
A small polyfill for Object.setprototypeof
Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.
Use node's fs.realpath, but fall back to the JS implementation if the native one fails
Safer Node.js Buffer API
Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.
Fast (and loose) selective `process.env` replacer using js-tokens instead of an AST
Create a stream that emits events from multiple other streams
A stream that emits multiple other streams one after another.
Merge multiple streams into one stream in sequence or parallel.
Execute code that is also shown to the user embedded in an HTML page.
ES2015 `Object.assign()` ponyfill
Support for representing 64-bit integers in JavaScript
Returns true if a number or string value is a finite number. Useful for regex matches, parsing, user input, etc.
Resolve any installed ES6 compatible promise
Fast deep equal

extend like a boss
An Object.keys replacement, in case Object.keys is not available. From https://github.com/es-shims/es5-shim
