Javascript code using Queryselectorall()

// 1) Write a Javascript function that takes TWO parameters: element and class. The element should be a DOM object, NOT a string. The class can be a string.

The function should add the designated class to any element matching that selector. what i have so far: var function addClassToElement(el, cls)f 12
