JavaScript: Filter out the specified values from a specified array

JavaScript fundamental (ES6 Syntax): Exercise-8 with Solution

Write a JavaScript program to filter out the specified values from a specified array. Return the original array without filtered values.

• Use Array.prototype.filter() and Array.prototype.includes() to pull out the values that are not needed.
• Set Array.prototype.length to mutate the passed in an array by resetting its length to 0.
• Use Array.prototype.push() to re-populate it with only the pulled values.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
 const pull = (arr, ...args) => {
  let argState = Array.isArray(args[0]) ? args[0] : args;
  let pulled = arr.filter((v, i) => !argState.includes(v));
  arr.length = 0;
  pulled.forEach(v => arr.push(v));
  return pulled;
};
let arra1 = ['a', 'b', 'c', 'a', 'b', 'c'];
console.log(pull(arra1, 'a', 'c'));
let arra2 =  ['a', 'b', 'c', 'a', 'b', 'c'];
console.log(pull(arra2, 'b'));

Sample Output:

["b","b"]
["a","c","a","c"]
