JavaScript How to remove certain element from Array
By：Roy.LiuLast updated：2019-08-11
In JavaScript, we can combine indexOf() and splice() to remove a certain element from an Array.
var array = [1, 2, 3, 4, 5];console.log(array)// I want remove num 4, find the index first, -1 if it is not present.var index = array.indexOf(4);if (index > -1) { // found array.splice(index, 1);// array = [1, 2, 3, 5];console.log(array);var lang = ['java', 'node js', 'javascript', 'pyhton'];console.log(lang)// I want remove node jsvar index = lang.indexOf(`node js`);if (index > -1) { lang.splice(index, 1);//lang = ['java', 'javascript', 'pyhton'];console.log(lang); |
