How to Write Better TypeScript

Learn how to make better use of Typescript’s strengths and features while involving React.

How to write better TypeScript

TypeScript: love it or hate it, you can’t deny the fact that it’s spreading like wildfire. In fact, according to the Stack Overflow 2019 developer survey, it was listed as the third most-loved programming language and the fourth most-wanted.

Now whether the survey accurately represents real-world sentiments is up for debate, but the fact remains that TypeScript is here, and it has come to stay. It’s so pervasive now that it has replaced vanilla JavaScript as the language of choice for many packages in the JS ecosystem, with some like Yarn even going as far as rewriting their entire codebase in TypeScript.

I feel one of the reasons for this meteoric rise to success has to be the fact that TypeScript, in essence, is just JavaScript. This makes the entry bar a lot lower for existing JavaScript developers, and the fact that it’s typed may also attract other devs who prefer the features typed languages provide.

This cuts both ways, too, because the ease of picking up TypeScript has led to some cases where the language is not being utilized as effectively as it could be. Many developers still write TypeScript like they’re writing JavaScript, and this brings with it some disadvantages.

We’ll be looking at some real-world code written in TypeScript that could be improved to make better use of the language’s strengths. This is by no means an exhaustive list, and I welcome you to list some you might have noticed in the comments section below.

Some of these examples involve React because I’ve noticed some instances where React code could be improved by simply making use of some TypeScript features, but the principles are by no means limited to React. Let’s dive in.

What You Can Learn about Setting from Classic Sitcoms

Giving your novel a strong sense of place is vital to doing your part to engage the readers without confusing or frustrating them. Setting is a big part of this (though not the whole enchilada — there is also social context and historic period), and I often find writing students and consulting clients erring on one of two extremes.

**Either: **Every scene is set in a different, elaborately-described place from the last. This leads to confusion (and possibly exhaustion and impatience) for the reader, because they have no sense of what they need to actually pay attention to for later and what’s just…there. Are the details of that forest in chapter 2 important? Will I ever be back in this castle again? Is there a reason for this character to be in this particular room versus the one she was in the last time I saw her? Who knows!

Or: There are few or no clues at all as to where the characters are in a scene. What’s in the room? Are they even in a room? Are there other people in th — ope, yes, there are, someone just materialized, what is happening? This all leads to the dreaded “brains in jars” syndrome. That is, characters are only their thoughts and words, with no grounding in the space-time continuum. No one seems to be in a place, in a body, at a time of day.

Everything aspect of writing a novel comes with its difficulties, and there are a lot of moving pieces to manage and deploy in the right balance. When you’re a newer writer, especially, there’s something to be said for keeping things simple until you have a handle on how to manage the arc and scope of a novel-length work. And whether you tend to overdo settings or underdo them, you can learn something from TV, especially classic sitcoms.

Your basic “live studio audience” sitcoms are performed and filmed on sets built inside studios vs. on location. This helps keep production expenses in check and helps the viewer feel at home — there’s a reliable and familiar container to hold the story of any given episode. The writers on the show don’t have to reinvent the wheel with every script.

Often, a show will have no more than two or three basic sets that are used episode to episode, and then a few other easily-understood sets (characters’ workplaces, restaurants, streets scenes) are also used regularly but not every episode.

TypeScript Vs JavaScript: Which one Is Better?

Despite their similarities (which are a lot), whether JavaScript (JS) is really better than TypeScript (TS) - or vice-versa - lies in their differences.

This article seeks to explain the current main contrasts between both languages and provides code examples of each. Further, we will explain whether JS and TS are object-oriented programming (OOP) languages and which one a developer should learn.

Finally, we will disclose which is better! As we know, JavaScript is a language that has highly contributed to the web’s success. Is it time for TypeScript to take over? Let’s find out.

Conclusion

What is JavaScript?

JavaScript (JS) is the most popular programming language in the world. It is considered a high-level language that helps to create interactive and dynamic web pages. Together with HTML and  CSS, JavaScript is also one of the core technologies for web applications and is highly characterized by its dynamic typing and just-in-time (JIT) compiler.

Plus, it is a multi-paradigm language due to its ability to support functional programming, imperative programming styles, and event-driven programming. JavaScript followed a client-side implementation (when the script runs on the user’s browser). However, it also has engines that allow server-side implementations (scripts run on the web server, and the response is customized according to each user’s request).
