This typescript package provides a set of frequently used utilities, types and svelte actions for building projects with Typescript and Svelte.

/**
 * Utils for working with promises.
 *
 * Promises are used in JavaScript to handle asynchronous operations. They are a way to handle the result of an asynchronous operation once it completes.
 *
 * You can await the completion of a promise using the `await` keyword. This will pause the execution of the current function until the promise resolves.
 * @module

 * Returns a promise that resolves after a delay.
 * @param ms - the number of miliseconds to wait before resolving the promise. Defaults to 0.
 * @returns Promise that resolves after the specified delay.
