Are you familiar with Mozilla's guide on combining strings using a delimiter in Angular2+?

I found myself in need of concatenating multiple string arguments with a specific delimiter, so after searching online, I stumbled upon a helpful guide on Mozilla's website that taught me how to achieve this using the arguments object.

function myConcat(separator) {
  var args = Array.prototype.slice.call(arguments, 1);
  return args.every(x => x === '') ? '' : args.join(separator);
}

After testing this code on a regular JS compiler like repl.it, it worked flawlessly! It's always satisfying to see something work as intended.

However, when integrating this code into my Angular 6 application, I encountered an error stating that I was passing too many arguments to the function, when it only expects one.

Is there a solution to making this work seamlessly in Angular 6?

Answer №1

Consider using rest parameters instead of the arguments object for better functionality:

function combineWords(delimiter, ...words) {
 return words.every(word => word === '') ? '' : words.join(delimiter);
}
