If there are any videos you'd like me to make or if you have any ideas on how to optimize this solution, let me know!

I like your methods, but for some reason it's not registering with me. I took a more naive approach with push() and pop():

push = function (x) {
while (this.primary.size() > 0) {

}

this.secondary.push(x);

while (this.secondary.size() > 0) {

}
};

pop = function () {
while (this.primary.size > 1) {

}
const popped = this.primary.pop();

while (this.secondary.size() > 0) {

}

};

It makes the peek() method more simplified though:

peek = function () {
return this.primary.peek();
};

I'll come back to this and try to make sure I get it with your more efficient way.
