Why can't Web Worker call a function directly?

Question

We can use the web worker in HTML5 like this:

var worker = new Worker(\'worker.js\');

but why can\'t we call a function like this?

Answer 1

This answer might be a bit late, but I wrote a library to simplify the usage of web workers and it might suit OP's need. Check it out: https://github.com/derekchiang/simple-worker

It allows you to do something like:

SimpleWorker.run({
  func: intensiveFunction,
  args: [123456],
  success: function(res) {
    // do whatever you want
  },
  error: function(err) {
    // do whatever you want
  }
})
