javascript remove g from regex

Question

Sometimes I need to use regex with g and sometimes without g.

let setreg = /set (\w+) (.+?)/g;
let setregnog = /set (\w+) (.+?)/;

Is there a way to just add a g to the end of setreg instead of using 2 vars.

Yes - you can use the RegExp() constructor.

let ptn = /foo/;
new RegExp(ptn, 'g'); //<-- with
new RegExp(ptn); //<-- without
