JavaScript Optional Chaining – An Introduction

Lawrence Chabela CSS & HTML, JavaScript, Problem Solving, Technology Snapshot 1 Comment

There is a new exciting feature coming to JavaScript in the not-so-far future. That feature is Optional Chaining. At this moment, Optional Chaining is in Stage 3 of the TC39 process, so it’s in late stages of the process and will be here soonish.

In general terms, Optional Chaining is an approach to simplify JavaScript expressions for accessing deeply nested values, array items, and methods when there is a possibility that a reference may be missing.

In this blog, we give an introduction to Optional Chaining in JavaScript. We discuss what problems Optional Chaining solves, the various ways you can use it, and relatable code examples.

With the introduction of .Net Core 3.0, Microsoft has built its own web UI framework.

Blazor allows developers to fully design and execute web pages purely with C# — it is meant to eliminate the need for JavaScript. The goal is also to hopefully limit the number of vulnerabilities found in front-end UI work.

In this post, we give an introduction to Blazor and a quick tutorial for getting started.

This is an in-depth learning series focused on a specific application: a JavaScript-based suite of single-page applications optimized for use in a microservice environment. We focus on telling the story of “why” and “how” it was built. 

In Part 2 of our Solid Foundations Learning Series, we covered quite a bit of ground surrounding the discovery of Handlebars files, creating navigation based off of those files, and the routing back to the server based on those files.

Now we’re going to dive back into the Handlebars pages and find out how we’re getting content into the pages when they’re rendered by the server.

Creating a UI Designer for Quick Development

User interface developers often come across situations that involve creating several web interface dashboards with similar architectures but with different UI controls and backend services serving real-time data. Examples of such Dashboards could be real-time stock quotes, or real-time performance of a factory floor. A common approach that many follow is to create an HTML5/CSS3 web application using a standard design pattern. …
