Lodash _.take() Method
The _.take() method is used to create a slice of an array with n elements from the beginning.
Syntax:
_.take(array, n)
Parameters: This method accept two parameters as mentioned above and described below:
- array: This parameter holds the query array.
- n: This parameter holds the number that represents the number of elements to take from array.
Return Value: This method returns an array of first n elements.
Example 1:
const _ = require('lodash'); let x = [1, 2, 'a', {'name': 'hello'}] let newArray = _.take(x, 3); console.log(newArray); |
Here, const _ = require('lodash') is used to import the lodash library into the file.
Output:
[ 1, 2, 'a' ]
Example 2:
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:
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.
