Inside the Concept
How can you combine two arrays?
In Javascript, we can combine two arrays by mean of concat() method
Syntax:
arr1.concat(arr2)
let arr1 = ["a", "b"];
let arr2 = ["c", "d"];
let result = arr1.concat(arr2);
["a", "b", "c", "d"]
Note:
Returns a new array
Original arrays remain unchanged
How can you copy elements from an array without altering the original?
Syntax:
arr.slice(start, end)
let arr = ["a", "b", "c", "d"];
arr.slice(1, 3);
//includes start index
// omits end index
["b", "c"]
Note:
Returns new array
In Javascript, use the slice() method to copy part of an array without altering the original.
