Functions with optional parameters
Today we are having fun refactoring legacy code. In our application there are functions with various optional parameters.
callRequest(method, params, data, headers, url)Only method is mandatory, all other parameters are optional. The status quo consists of each parameter being checked for existance, not very pretty...
callRequest(method, params, data, headers, url) {
if (headers && headers.length > 0) {
...
}
...
}
