Isn't it already solvable by:
const SizedArray = (size) => class SizedArray extends Array
{
constructor(...args) {
if(args.length > size) throw new SyntaxError('Argument size is too big.')
super(...args)
}
push(i) {
if(this.length + 1 > size) throw new SyntaxError('Cannot push
items anymore, array too big.')
super.push(i)
}
}
const arr = new (SizedArray(5))?
