yeah that's basically it, I know you're leaning into your existing knowledge (of likely C-based stuff) but your line of thinking is about right about how you're inferring things ... naming and stuff gets a bit "different" or less serious when you go into JS land sometimes.
What's funny is if this were a real job interview question and you answered in the way that you did ... the way you answered it told me more about yourself and your qualifications than just getting it exactly right
