Delete an specific element in an Array in javascript

Question

I want to delete an specific element in an array. I have this for example: A = [10,54,65,12] and I want to delete the '65' number. How can I do this?

I try the pop() function but this deletes my last number.

Answer 1

You can use splice() with indexOf()

var A = [10,54,65,12];
A.splice(A.indexOf(65), 1);
console.log(A)

Answer 2

You need to find the index of element using .indexof() and then remove it using .splice():

var index = A.indexOf(65);
if (index > -1) {
 A.splice(index, 1);
}

Answer 3

Use splice & indexOf

var a = [10,54,65,12]
var index = a.indexOf(65);
if (index > -1) {
 a.splice(index, 1);
}
console.log(a)

Answer 4

You can use lodash library for doing this. '_.remove'

var A = [10,54,65,12];

_.remove(A, 65);

console.log(A)

// [10,54,12]
