Lodash _.assign() Method

Lodash _.assign() method is used to assign the enumerable string keyed properties of the given source objects to the destination objects. The source objects are applied from left to right and any subsequent sources overwrite the property assignments of the previous sources.

Syntax:

_.assign( dest_object, src_obj );

Parameters:

• dest_object: This is the destination object.
• src_obj: These are the source objects.

Return Value:

This method returns an object.

Example 1: In this example, we are assigning a value to an object by using the _.assign() method.

// Defining Lodash variable 
const _ = require('lodash');

// Using the ._assign() method
console.log(
    _.assign({ a: 1, c: 3 }, { a: 0 })
);

Output:

{ a: 0, c: 3 }

Example 2:  In this example, we are assigning two object values to an object by using the _.assign() method.

// Defining Lodash variable 
const _ = require('lodash');

// Using the ._assign() method
console.log(
    _.assign({ a: 0 }, { a: 1, c: 3 }, { d: 4 })
);

Output:

{ a: 1, c: 3, d: 4 }
