In recent years, TypeScript has gained popularity as a statically-typed superset of JavaScript, promising improved code quality and bug prevention. However, taking a closer look reveals that TypeScript may not be the silver bullet some developers believe it to be.

Type Gymnastics

Working with TypeScript often feels like navigating through a maze of type gymnastics. While types can provide clarity, the complexity they introduce may become a hindrance, especially in projects where simplicity and agility are crucial.

A Viable Alternative: Comments and JSDoc

The need for TypeScript can be mitigated by adopting good coding practices, such as using proper comments and JSDoc. Well-documented code not only enhances readability but also eliminates the necessity for extensive type annotations.

Addressing JS Errors: A Matter of Code Structure

JavaScript errors may seem perplexing at first glance, but a careful examination often reveals that code restructuring, adopting functional or generic approaches, can alleviate these issues. Many problems arise from anti-patterns in code organisation rather than inherent flaws in JavaScript itself.

Naming Matters: A Fundamental Principle

Properly naming variables and functions is a fundamental principle of good coding. Clarity in nomenclature not only improves code comprehension but also reduces the likelihood of errors, rendering excessive type checking less imperative.

Following the Herd

People in general, tend to follow trends without critical evaluation. Before embracing TypeScript en masse, it’s essential to consider whether it aligns with the specific needs and goals of your project.

Conclusion

Transforming a dynamically typed language into a statically typed one is not be necessary. If you don’t understand why String + Number = StringNumber, then it is your lack of knowledge about the language you are working with. You can’t expect PHP to work like Swift. Programming languages have their own pros and cons so appreciate the good and accept the bad.

But then again, you do you.
