Lodash _.drop() Method

  • Last Updated : 02 Feb, 2022

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers etc. 
The Lodash.drop() method is used to drop the elements in a given array.

Syntax :

Lodash.drop(array, number)

Parameters:

  • Array: It is the original array from which the elements are to be removed.
  • Number: It is the number of elements to be removed from the array.

Note: The elements are removed from the index 0 of the array.

Return Value: It returns the sliced array.

Example 1:

Javascript




// Requiring the lodash library
const _ = require("lodash");
 
// Original array
let array = ["a", "b", "c", "d"]
 
// using drop() method to remove
// first two elements
let newArray = _.drop(array, 2)
 
// Printing original array
console.log("before : ", array)
 
// Printing array after applying
// drop function
console.log("after : ", newArray)

Output:

Example 2: If elements to be removed from the right side of the array we use _.dropRight() function.

Javascript




// Requiring the lodash library
let lodash = require("lodash");
 
// Original array
let array = [1, 2, "a", "b", "c", "d"]
 
// Using drop() method to remove
// first 2 elements from right
let newArray = lodash.dropRight(array, 2)

console.log("before : ", array)

// drop function
console.log("after : ", newArray)
