Example 1: In this example, we are creating a new array having 3 elements of an old array by the use of the lodash _.take() method.
javascript
const _ = require( 'lodash' ); let x = [1, 2, 'a' , { 'name' : 'hello' }] let newArray = _.take(x, 3); console.log(newArray); |
Output:
[ 1, 2, 'a' ]
Example 2: In this example, we are creating a new array having 2 elements of an old array by the use of the lodash _.take() method.
javascript
const _ = require( 'lodash' ); let x = [ { 'name' : 'lodash' }, { 'name' : 'npm' }, { 'name' : 'nodejs' } ] let newArray = _.take(x, 2); console.log(newArray); |
Output:
[ { name: 'lodash' }, { name: 'npm' } ]
Example 3: In this example, we are creating a new array having 5 elements of an old array by the use of the lodash _.take() method.
javascript
const _ = require( 'lodash' ); let x = [1, 2, 3, 4, 5, 6, 7] let newArray = _.take(x, 5); console.log(newArray); |
Output:
[ 1, 2, 3, 4, 5 ]
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
