wait

Syntactic sugar for setTimeout and setInterval.

wait(time, callback, id)

Sugar for setTimeout.

wait(100, function(){
    // Do something in 100 milliseconds
});

wait('2s', function(){
    // Do something in 2 seconds
});

wait('2 minutes', function(){
    // Do something in 2 seconds
}, 'awesomeId');

repeat(time, callback, id, callBefore = false)

Sugar for setInterval.

If callBefore is true the callback will be executed before the interval.

repeat(100, function() {
    // Do something every 100 milliseconds
});

repeat('1 min', function() {
    // Do something every minute
}, 'awesomeId');

repeat('1 min', function() {
    // Run immediately and every minute
}, true);

repeat('1 min', function() {
    // Run immediately and every minute
}, 'awesomeId', true);

until(condition, callback, interval = 100, id)

Runs the callback function when the condition is true. If you don't specify an interval the condition will be check every 100 milliseconds.

var condition = function() {
    return 1 == 1;
};

until(condition, function() {
    // Do something when 1 == 1
});

until(condition, function() {
    // Check every second if 1 == 1 and do something.
}, '1 second');

until(condition, function() {
    // Check every second if 1 == 1 and do something.
}, 150, 'coolId');

clear

Syntactic sugar for clearInterval and clearTimeout

The clear() method can be used in 3 ways:

// Will clear all intervals and timeouts that where created with an id
clear();

// Will clear a timeout or interval given an id.
clear(id);

// The id can be two things.
var timeout = wait(100, callback);
clear(timeout);

wait(100, callback, 'awesome-id');
clear('awesome-id');

// Will clear all timeouts and intervals in an array.
clear([timeout, 'awesome-id']);

time

Time can be specified in various formats:

If time is a number, it will be interpreted as milliseconds.

100, 1 second, 3 minutes, 1 hour, 3 secs, 1 min, 2 hrs, 1s, 3m, 2h
