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 js var index = lang.indexOf(`node js`); if (index > - 1 ) { lang.splice(index, 1 ); //lang = ['java', 'javascript', 'pyhton']; console.log(lang); |
