The best explanation I've seen so far. that I've seen. I've seen other explanations used on forms and I've kinda understood the concept behind it but it has never fully clicked in my head until now :D

sir,
how to do the same thing using string instead of integer number

[ridhwaans]

this didnt work, it returned expected an assignment or function call and instead saw an expression. To fix it, added () such as handleAdd to handleAdd() in your Child example
