Define a lazily evaluated property on an object

Helps you create value objects and refined types for safer software

Persistent ordered mapping from strings

create value by measuring lots

Transforms css values and at-rule params into the tree

Match a Unicode property or property alias to its canonical property name per the algorithm used for RegExp Unicode property escapes in ECMAScript.

Copy a descriptor from object A to object B

Use property paths like 'a.b.c' to get a nested value from an object. Even works when keys have dots in them (no other dot-prop library we tested does this, or does it correctly).

Set nested properties on an object using dot notation.

A fast fifo implementation similar to the one powering nextTick in Node.js core

Simple key-value storage with support for multiple backends

Returns true if a value exists, false if empty. Works with deeply nested values using object paths.

Delete nested properties from an object using dot notation.

Returns true if an object was created by the `Object` constructor, or Object.create(null).

Set an array of unique values as the property of an object. Supports setting deeply nested properties using using object-paths/dot notation.

Create and parse Content-Disposition header

Map object keys and values into a new object

Array manipulation, ordering, searching, summarizing, etc.
