How do I remove a particular element from an array in JavaScript?
Find the index
of the array element you want to remove, then remove that index with splice
.
The splice() method changes the contents of an array by removing existing elements and/or adding new elements.
var array = [2, 5, 9];
console.log(array)
var index = array.indexOf(5);
if (index > -1) {
array.splice(index, 1);
}
// array = [2, 9]
console.log(array);
The second parameter of splice
is the number of elements to remove. Note that splice
modifies the array in place and returns a new array containing the elements that have been removed.
