let lodash = require("lodash");
 
// Original array
let array1 = [[1, 12], [12, 8], 7, 8]
 
// Using lodash.slice() method
let newArray = lodash.slice(array1, 1, 3);
 
// Printing original Array
console.log("original Array1: ", array1)
 
// Printing the newArray
console.log("new Array: ", newArray)

                    

Output: 


Example 2: In this example, we are slicing an array and the given end index is not in range of the size of the array.

let lodash = require("lodash");
 
// Original array
let array1 = [[1, 12], [12, 8], 7, 8, 3, 4]
 
// Using lodash.slice() method
let newArray = lodash.slice(array1, 1, 10);
 
// Printing original Array
console.log("original Array1: ", array1)
 
// Printing the newArray
console.log("new Array: ", newArray)

let lodash = require("lodash");
 
// Original array
let array1 = []
 
// Using lodash.slice() method
let newArray = lodash.slice(array1, 1, 2);
 
// Printing original Array
console.log("original Array1: ", array1)
 
// Printing the newArray
console.log("new Array: ", newArray)

                    

Output: 

Examples 4: In this example, we are slicing an array where start and end index are not given.
