How to convert Php regular expression into js

I have a regular expression in PHP and its working fine but i want to use it in js as well can any please tell me how to do that i am not much familiar with it

In php this expression is working like this it allow hyphen symbol (-) between number and character but remove hyphen symbol between characters and replace it with white space Like if i use any of this string 

$string ="Al-Abbas - Manama - 100" or
$string ="100 - Al-Abbas - Manama"

$repl = preg_replace('/\d\h*-\h*(*SKIP)(*F)|-(?!\h*\d)/', ' ', $string);

after this i am getting this output 

Al Abbas Manama - 100
100 - Al Abbas Manama

i want to do same like this in javascript how can i convert this expression in javascript or any other way to do like this in javascript.

you can use this pattern that captures what you want to avoid. Since \h doesn't exists in javascript you can emulate it using [^\S\r\n]. The replacement function returns the group when it exists or a space:

mystr = mystr.replace(/(\d[^\S\r\n]*-)|-(?![^\S\r\n]*\d)/g, function (_, g) {
    return g ? g : ' '; });

var str="100 - Al-Abbas - Manama";
var newstr = str.replace(/\d\h*-\h*(*SKIP)(*F)|-(?!\h*\d)/, ' ');
