Question

I started learning JavaScript last week, I saw this code yesterday and I did some research about it, but now I can’t figure what it does:

var y=document.forms['post'];
var x=y.message.value;
x=x.replace(/</gi,'(').replace(/\</gi,'(');
y.message.value=x;

Answer 1

Here is my understanding of it:

1. Variable y holds your form which has name = post.
2. Variable x holds value property of tag message.
3. Replace < and put ( in message.
4. Assign new message tag x to original y
