Minimize redundancy in the process of adding functions to a function queue

Minimize redundancy in the process of adding functions to a function queue

Currently, I am delving into JavaScript animations and utilizing multiple functions to add components to the animation queue. The structure of these functions is quite repetitive as shown below:

function foo(arg1, arg2) {
    _eventQueue.push(function() {
        // actual logic
    }
}

However, I have been contemplating ways to minimize this redundancy to avoid repeatedly including the "_eventQueue" line in each function. Is there a way to create a helper function that can take any function as an argument and return a new function augmented to automatically join the event queue? My main obstacle lies in retaining access to the original function's arguments during this process, which poses a challenge.

Answer №1

If you're in search of the arguments keyword, it refers to an array-like object that holds the arguments passed to the current function.

Here's a quick example:

function generateMultiplicator(func) {
    return function() {
        var internalArguments = arguments;

        _queue.push(function() {
            return func.apply(window, internalArguments);
        });
    };
}
