Object syntax return statements

I need help understanding why these are different…

  **Your code so far**
  isEmpty() {
    return this.collection.length === 0;
  clear() {
    return (this.collection.length = 0);

Challenge: Create a Stack Class

Link to the challenge:

return this.collection.length === 0
Here you compare collection.length to zero. It can be rewritten as

if (this.collection.length === 0) {
   return true;
} else return false;

return (this.collection.length = 0)
And here you’re setting collection.length to zero which leads to clearing the collection
