Object

Object namespace.

Installation

npm install @stdlib/object

Usage

var ns = require( '@stdlib/object' );

ns

Object namespace.

var o = ns;
// returns {...}

The namespace contains the following:

• anyInBy( object, predicate[, thisArg ] ): test whether at least one property in an object passes a test implemented by a predicate function.
• anyOwnBy( object, predicate[, thisArg ] ): test whether at least one own property of a provided object passes a test implemented by a predicate function.
• assignIn( target, source1[, source2[,...,sourceN]] ): copy enumerable own and inherited properties from one or more source objects to a target object.
• assign( target, source1[, source2[,...,sourceN]] ): copy enumerable own properties from one or more source objects to a target object.
• bifurcateIn( obj, [options,] predicate ): split an object's own and inherited property values into two groups according to a predicate function.
• bifurcateOwn( obj, [options,] predicate ): split an object's own property values into two groups according to a predicate function.
• capitalizeKeys( obj ): convert the first letter of each object key to uppercase.
• commonKeysIn( obj1, obj2[, obj3[,...,objN]] ): return the common own and inherited property names of two or more objects.
• commonKeys( obj1, obj2[, obj3[,...,objN]] ): return the common own property names of two or more objects.
• Object( value ): object constructor.
• deepGet( obj, path[, options] ): get a nested property value.
• deepSet( obj, path, value[, options] ): set a nested property value.
• everyInBy( object, predicate[, thisArg ] ): test whether all properties (own and inherited) of an object pass a test implemented by a predicate function.
• everyOwnBy( object, predicate[, thisArg ] ): test whether all own propertes of an object pass a test implemented by a predicate function.
• forIn( obj, fcn[, thisArg ] ): invoke a function for each own and inherited enumerable property of an object.
• forOwn( obj, fcn[, thisArg ] ): invoke a function for each own enumerable property of an object.
• inverseBy( obj, [options,] transform ): invert an object, such that keys become values and values become keys, according to a transform function.
• inverse( obj[, options] ): invert an object, such that keys become values and values become keys.
• lowercaseKeys( obj ): convert each object key to lowercase.
• moveProperty( source, prop, target ): move a property from one object to another object.
• noneInBy( object, predicate[, thisArg ] ): test whether every property of an object fails a test implemented by a predicate function.
• noneOwnBy( object, predicate[, thisArg ] ): tests whether every own property of an object fails a test implemented by a predicate function.
• someInBy( obj, n, predicate[, thisArg ] ): test whether an object contains at least n properties which pass a test implemented by a predicate function.
• someOwnBy( obj, n, predicate[, thisArg ] ): test whether an object contains at least n own properties which pass a test implemented by a predicate function.
• uncapitalizeKeys( obj ): convert the first letter of each object key to lowercase.
• uppercaseKeys( obj ): convert each object key to uppercase.

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var ns = require( '@stdlib/object' );

console.log( objectKeys( ns ) );
