JavaScript - remove first n elements from array
0 points
In this article, we would like to show you how to remove first n elements from an array in JavaScript.
Quick solution:
xxxxxxxxxx1
var array = ['a', 'b', 'c', 'd'];2
var n = 2;3
4
array.splice(0, n);5
6
console.log(array); // [ 'c', 'd' ]
In this example, we create a reusable arrow function that removes the first n elements from array.
The number of elements to remove can't be greater than array.length, otherwise the function returns unchanged array.
xxxxxxxxxx1
const removeElements = (array, n) => {2
if (n < array.length) {3
array.splice(0, n);4
}5
return array;6
};7
