How can I delay a function with parameter?

Question

I am trying to make a game, where the machine takes a while to respond, so the user actually knows the machine is 'deciding' its move. I need to use the setTimeout() method, but I want to specify a parameter to my function.

Example: setTimeout(myFunction('p'), 1000);. The problem is that when I specify the parameter, the function runs perfectly fine, but there´s no delay.

When you write setTimeout(myFunction('p'), 1000);, myFunction('p') is evaluated and then setTimeout(returnValueOfMyFunction, 1000) is evaluated.

This code will run the anonymous function at the correct time:

setTimeout(function (){myFunction('p')}, 1000);

You can bind your function like this, so after the time, it will be executed:

setTimeout(myFunction.bind(this, 'p'), 1000);

Just wrap the function call with parameters in another parameterless function definition.

Example:

setTimeout(function() {
    myFunction('p');
}, 1000);
