Question

Whatever string is given I have to see if there is exactly one space after and before =, If it is more than one space in either side I have to reduce that to one and if there is none, I have to insert one.

How should I do that ? String can contain anything.

Thanks

You can do this:

str = str.replace(/ *= */g, " = ");

This will replace all = characters regardless of how many spaces it is surrounded by. The * quantifier will match as most spaces as possible while allowing even no spaces at all.
