I would like a JavaScript function to have optional arguments which I set a default on, which gets used if the value isn't defined. In Ruby you can do it like this:
def read_file(file, delete_after = false)
# code
end
Does this work in JavaScript?
function read_file(file, delete_after = false) {
// Code
}
