Caching

hasOwn

Object.prototype.hasOwnProperty

toString

Object.prototype.toString

slice

Array.prototype.slice

trim

String.prototype.trim

Nothing

noop

Returns undefined.

getThis

Returns this.

Typing

type( obj )

Returns type reported by toString.

isNumber( number )

isArray( array )

isFunction( fn )

isPlainObject( obj )

isEmpty( obj [, andPrototype ] )

Set andPrototype to something truthy and obj will have to be empty all the way through.

Iterating

each( obj, callback )

Like jQuery, with a callback signature of key, value, obj.

forEach

Like ES5 forEach, with a callback signature of value, key, obj.

Extending

extend( [ flags, ] target, source, [ ...sourceN ] )

Like jQuery, with an option flags string.

• 'deep' : Same as the optional Boolean flag in jQuery
  

• 'own' : Restricts extended properties to those filtered by `Object.hasOwnProperty`
  

• 'all' : Includes keys with undefined values
  

Array/Object Composition

flatten

Extracts elements of nested arrays.

keys( obj )

Returns an object's keys in an ordered string array.

invert( array )

For an array whose values are unique key strings, this returns an object that is a key-value inversion of array.

setAll( obj, value )

Set every key in obj to value.

nullify( obj )

Set every key in obj to null.

nullHash( array )

Given an array of keys, return an object with those keys all set to null.

Miscellaneous

stringFunction( fn )

Return the function fn, with its toString method set to itself. Might break stuff, like type, but can be useful for, say, devtools-inspecting the value of a getter.

valueFunction( fn )

Same as above, but for valueOf instead of toString.
