How can I add variable inside RegEx

Question

I am not finding solution to add variable inside following RegEx

val.replace(/[^\d.]/gm,'')

Basically I need to change the . to variable.
Something like

val.replace("/[^\d"+sepaeator+"]"/gm,'')

Use the constructor `new RegExp`. See [documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp). — trincot, Jul 23 '18 at 14:20

Use a RegExp instance (mdn):

const regex = new RegExp(`[^\d${separator}]`, 'gm');
val.replace(regex, '');
