Remove ’ on string using regex

Question

I have a word like this What's On . How to remove space and ' ?

I can remove space like so data.caption.replace(/ +/g, "") How to do the other part?

Answer 1

You can use [] to provide a character set. So in this case, the following would match against the weird quote and a space.

/[’ ]+/g

Answer 2

This expresion might simply work:

\s*’

which checks for 0 or more spaces prior to ' .

 console.log("What 's On ?".replace(/\\s*'/,"")); console.log("What 's On ?".replace(/[\\s']+/,"")); 

Or if we wish to replace all spaces:

 const regex = /([^\\s']+)|(.+?)/gm; const str = `What 's On ?`; const subst = `$1`; // The substituted value will be contained in the result variable const result = str.replace(regex, subst); console.log(result);
