myString.replace( VARIABLE, “”) … but globally

Question

How can I use a variable to remove all instances of a substring from a string? (to remove, I\'m thinking the best way is to replace, with nothing, globally... right?)

Well, you can use this:

var reg = new RegExp(oldWord, "g");
myString.replace(reg, "");

or simply:

myString.replace(new RegExp(oldWord, "g"), "");
