Javascript Promise

Wed, 22 Oct 2025 21:00:00 -0500

A Promise is a guaranteed placeholder value for what a function or series of functions will return.

It’s a promise to return a value eventually.

The function swears this time is different. You can trust it. It swears it’ll get it back to you in no time.

If you haven’t already, check out my post on JavaScript Callbacks where we dove into callback hell and why we desperately needed something better. Spoiler: Promises are that something better.

Why Typescript Interface Names Should Start With "I"

TypesScript interface names should start with “I” because while a type is real, an interface is purely “I"maginary.

Netlify Single Page App 404 Redirect

Mon, 08 Nov 2021 16:36:15 -0600

tl;dr

Add a netlify.toml file to the root of your project if one doesn’t exist.

Add the following setting to redirect all routes to your single-page-application.

[[redirects]]
from = "/*"
to = "/index.html"
status = 200

The netlify.toml file should now look something like this:

Background

I started using Netlify for a number of side projects and a recent start-up.

As many do, I started using a single-page-applications (SPA) framework to build up the front-end.

Javascript Callbacks

Mon, 03 May 2021 15:00:00 -0500

Brief History of Callbacks

It all starts with the callback function.

A callback function is just a plain JavaScript function that is passed into another function as an argument.

That’s it. Nothing special.

This callback function can be used to return data, or to signal that some event took place.

If you’ve worked with web development you’ve definitely crossed paths with callbacks.

Think of a button click event for a web page.

New Course: Event Handling in jQuery

Event Handling in jQuery

My newest course, “Event Handling in jQuery” went live at Pluralsight!

GitHub Files - Event Handling in jQuery

Course Description

Open your web browser and immediately you’ve triggered an event.

With every opening of a page, click of a button, or movement of the mouse, you’ve probably triggered dozens of events.

Ever get prompted that you’ll be logged out of a site due to inactivity? You can even trigger an event by doing nothing for just long enough.

Javascript Function Parameters and Arguments Explained

JavaScript Function Signatures

Alright, you’ve probably seen functions before. Something like this maybe?

 function doSomething(name, desc, task) {
 // did something
 }

This function, named doSomething, takes three parameters as part of its function signature. These parameters named name, desc, and task are the names of the values being sent into the function.

I’m going to use a sportsball reference here so be warned. You can think of the function as a net that gets various types of objects tossed into the hoop ( ) where it triggers sports points.
