SpeedyPromise

Speedy includes its own implementation of promises. A SpeedyPromise works just like a standard promise. SpeedyPromises are designed for real-time applications. There are some subtle differences behind the scenes, but you need not be concerned with those.

Instantiation

Speedy.Promise

new Speedy.Promise(executor: function): SpeedyPromise

Creates a new SpeedyPromise. This works just like the constructor of a standard promise.

Arguments

• executor: function. A function that takes two functions as arguments:
  • resolve: function. To be called when the promise is resolved.
  • reject: function. To be called when the promise is rejected.

Returns

A new SpeedyPromise.

Example

function sleep(ms)
{
    return new Speedy.Promise((resolve, reject) => {
        if(ms >= 0)
            setTimeout(resolve, ms);
        else
            reject(new Error('Invalid time'));
    });
}

sleep(2000).then(() => {
    console.log('2 seconds have passed');
}).catch(error => {
    console.error(error.message);
}).finally(() => {
    console.log('Done!');
});
