Lodash _.drop() Method
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) // Printing original array console.log( "before : " , array) // Printing array after applying // drop function console.log( "after : " , newArray) |
Output:
Example 3: If number greater then the size of array is given then it returns the empty array as given in the below given example.
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 10 elements let newArray = lodash.drop(array, 10) // Printing original array console.log( "before : " , array) // Printing array after applying // drop function console.log( "after : " , newArray) |
