JavaScript - remove space after a specific char

I've found many solutions in JavaScript to remove all spaces in a string with \s. But I can't found a solution for my specific problem. I want to transform "2* 2 +3* 5" in "2*2+3*5" (no more space after '*'), I've tried with

mot = mot.replace(/*\s/g, '*');

But it doesn't work, does anyone have the answer?

mot = mot.replace(/(\*)\s/g, "$1");

Note that you have to use \ before a * because * is a reserved character. With this, you can also add more characters with no whitespace allowed after, like * and + here:

mot = mot.replace(/([*+])\s/g, "$1");

Now that the * is in a [] you don't need to esacpe it. And lastly, to remove multiple whitespaces at once, use

mot = mot.replace(/([*+])\s+/g, "$1");

You need to escape the * character.

Try this: "2* 2 +3* 5".replace(/\*\s/g,'*')
