Question

I have string it contains some code. I want to make some changes on it. There is a for loop I want to modify with js.
The loop:

"for i in 0..10 loop"

I want it to be:

"for (var i=0; i<10; i++)"

It sounds me very complicated. What should be the easiest approach?

Answer 1

Here’s a way to do it, but probably not the best:

var str = "for i in 0..10 loop",
    str = str.replace("i in ", "(var i="),
    str = str.replace("..", "; i<"),
    str = str.replace(" loop", "; i++)");
console.log(str);

Example.
