Mutates the original array to filter out the values specified.
Use Array.prototype.filter()
and Array.prototype.includes()
to pull out the values that are not needed.
Use Array.prototype.length = 0
to mutate the passed in an array by resetting it’s length to zero and Array.prototype.push()
to re-populate it with only the pulled values.
const pull = (arr, ...args) => {
let argState = Array.isArray(args[0]) ? args[0] : args;
let pulled = arr.filter(v => !argState.includes(v));
arr.length = 0;
pulled.forEach(v => arr.push(v));
};
let myArray = ['a', 'b', 'c', 'a', 'b', 'c'];
pull(myArray, 'a', 'c'); // myArray = [ 'b', 'b' ]
