Invoke object as a function (JavaScript/TypeScript)

If I have a logging class named Logger, can I define a special method within the class to be called when the instance of the class is used as a function? So instead of using log.method(), it would be possible to use log() directly like this:

log(...)

In PHP, by implementing the __invoke() magic method in a class, you can achieve similar functionality.

Answer №1

function LoggingFunction() {
  return function log(argument1, argument2) {
    //@TODO: utilize the arguments passed to the function
    // or access the arguments property to
    // create a log

    console.log(log.arguments);
  }
}
logger = new LoggingFunction();
logger('explosion', 456, 'carpe diem');

This approach should address the issue you are seeking to resolve. Any optimizations or alternative methods for implementation may be suggested in the responses below.
