Let's also not forget to capitalize "forEach" correctly; that we need
parentheses around the conditional; that we want to compare, not assign; that
there is no such JavaScript keyword as "then"; and that in the revised code,
there is no variable "i":
list.forEach(function (file) {
if (file.ext == ext) {
console.log(file);
}
});
There's also no such thing as a "list" in JavaScript; it's called an "array".
