Accessing a character in a string?

Question

I am making a timer. I need to insert a ":" in between minutes and hours. it will look something like this:
<input value=456 placeholder="00:00"></input>

Answer 1

Suppose the name of your string is s.
Then you can do this:
s.charAt (0)+":"+s.slice (1)
P.s if the first number is less than 10 you need to add a zero before it .
like for input 456 it will be 04:56
