To TypeScript or Not: Navigating the Debate
Written on
Chapter 1: Introduction to TypeScript
I've grown weary of encountering articles that present subjective views on TypeScript. Are these pieces simply designed to draw attention? And why do they tend to be so lengthy?
Choosing to implement TypeScript is a significant yet straightforward choice. Like any tool, it comes with its own set of advantages and drawbacks. Let’s delve into the discussion.
Section 1.1: Advantages of TypeScript
When utilized effectively, TypeScript primarily serves one purpose: it introduces static analysis to JavaScript.
JavaScript itself lacks this feature as it is a loosely typed language, which is precisely why TypeScript was created. Static analysis helps identify type-related issues, leading to enhanced code quality, provided that developers manage these issues correctly. Thus, TypeScript contributes positively to code quality.

Section 1.2: Drawbacks of TypeScript
On the flip side, coding with TypeScript often requires more time.
Firstly, defining types can be time-consuming and tedious. While some of this burden can be alleviated through code generation, it still demands time.
Secondly, developers are compelled to consider all possible edge cases from the outset.
Thirdly, since JavaScript does not enforce type safety, grappling with type definitions can be a common challenge.
Using TypeScript necessitates patience, dedication, and, most importantly, time.
Chapter 2: The Reality of Code Quality
I personally encounter few bugs in my code, and when they do arise, they are generally straightforward to resolve.
However, have you considered the implications of future code modifications? What about the risk of leaky abstractions?
The crux of the matter is that your skills as a developer aren't the sole determining factor. As applications expand, TypeScript will help catch potential issues.
For instance, we employ TypeScript to generate types directly from a service. If there are any breaking changes in that service, TypeScript will flag errors and pinpoint all locations in the code where these issues occur.
Again, it’s not just about your abilities as a developer; TypeScript will catch errors at some stage, somewhere.
Conclusion: Making the Decision
While the choice is indeed pivotal, the decision-making process surrounding TypeScript is relatively straightforward.
- Do you prioritize quality over speed?
- Are you prepared to implement TypeScript correctly, focusing solely on type-safe features?
- When TypeScript raises concerns, will you respond to them appropriately?
If you answered "yes" to all these questions, then TypeScript is a suitable choice for you.
If your answer to the first question is affirmative, but negative for the next two, consider whether you can turn those "no" responses into "yes."
And if your answer is "no" across the board, TypeScript may not be for you. There are alternative approaches to building high-quality applications without relying on TypeScript (hello, CI/CD).
