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?)

According to the docs at MDN, you can do this:

var re = /apples/gi;
var str = 'Apples are round, and apples are juicy.';
var newstr = str.replace(re, 'oranges');
console.log(newstr);  // oranges are round, and oranges are juicy.

where /gi tells it to do a global replace, ignoring case.
