Kevin Neema Brian it's nice that you want to educate, but the Q&A section is meant to help the creator of a question to solve his/her problems with a specific topic. Your post belongs in your personal feed. That said I'm sorry to tell you that your explanation is wrong. b = a++ or b = ++a both consist of an assignment to b and an increment of a. Pre/post increment specified the order of those operations. Pre (b=++a): a is increased first, then the incremented value of a is assigned to b Post (b=a++): the value of a is assigned to b, and after that a is incremented In all cases only a is incremented

PRE increment: add 1 BEFORE evaluation in expression POST increment: add 1 AFTER evaluation in expression var pre = 0, post = 0; console.log(++pre + pre); // 2 (1+1) console.log(post++ + post); // 1 (0+1)
