var repl = ['0', '1'];
var pattern = /\?/g;
var numMatches = str.match(pattern).length;
for(var j=0; j<numMatches; j++){
for(var i=0; i<repl.length; i++){
console.log(str.replace(pattern, repl[i]));
}

Works only if there's 1 '?'. For example 1?1? should return ['1010', '1011', '1110', '1111'], instead returns ['1010', '1010', '1111', '1111']
