javascript - remove array element on condition

Question

I was wondering how I\'d go about implementing a method in javascript that removes all elements of an array that clear a certain condition. (Preferably without using jQuery)

Answer 1

You can use Array filter method.

The code would look like this:

ar = [1, 2, 3, 4];
ar = ar.filter(item => !(item > 3));
console.log(ar) // [1, 2, 3]
