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?)

if I have these 2 strings,

myString = This sentence is an example sentence.

oldWord =  sentence

then something like this

myString.replace(oldWord, );

only replaces the first instance of the variable in the string.

but if I add the global g like this myString.replace(/oldWord/g, ); it doesn't work, because it thinks oldWord, in this case, is the substring, not a variable. How can I do this with the variable?
