Using Regular Expressions for Search/Replace

I have a String like this item width200height300. The values of width an height may be different. Like this item width100height100 or item width50height300.

How can you search and replace widthxxxheightxxx with Regular Expressions?

function replacer(match, p1, p2){
  // do something with p1 or p2
  return "item width"+p1+"heigth"+p2;
};
newString = "item width50height300".replace(/width(\d+)height(\d+)/, replacer);
console.log(newString);
