Copy enumerable own properties from one or more source objects to a target object.
npm install @stdlib/object-assignWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Copy enumerable own properties from one or more source objects to a target object.
``bash`
npm install @stdlib/object-assign
`javascript`
var assign = require( '@stdlib/object-assign' );
#### assign( target, source1\[, source2\[,...,sourceN]] )
Copies enumerable own properties from one or more source objects to a target object.
`javascript
var x = {
'a': 'beep'
};
var y = {
'b': 'boop'
};
var z = assign( x, y );
var v = z.b;
// returns 'boop'
var bool = ( z === x );
// returns true
`
- If a property key is present in multiple sources, the property from the last source that defines the key prevails.
- The target object is mutated.
- Both string and symbol properties are copied.
`javascript
var assign = require( '@stdlib/object-assign' );
var obj1 = {
'name': 'Jane',
'age': 29
};
var obj2 = {
'country': 'US',
'city': 'San Francisco'
};
var obj3 = {
'hobby': 'Reading'
};
var result = assign( obj1, obj2, obj3 );
// returns { 'name': 'Jane', 'age': 29, 'country': 'US', 'city': 'San Francisco', 'hobby': 'Reading' }
