In the event you come from an object-oriented language like C# or Java, you’ll discover many acquainted options within the record that TypeScript provides. My favourite ones embody the addition of enums, interfaces, entry modifiers, namespaces, generics, and plenty of extra.
TypeScript is nice for large-scale net purposes, as you’ll be able to write frontend and backend code with it. On the backend, it is advisable set up a library known as ts-node to execute TypeScript code in a Node.js environment.
In 2022, TypeScript joined the world’s top 5 most used languages. That is unsurprising, as a result of TypeScript continually develops, provides new options, and has a unbelievable developer group that TypeScript’s workforce listens to.
When utilized in pairs with a more recent IDE like Visible Studio Code, TypeScript gives nice Intellisense options equivalent to code hinting and code completion. These options assist enhance the velocity of the event of this system.
Additionally, TypeScript permits utilizing some ES6 and ES7 candidate options not but supported by main browsers. For instance, the elective chaining operator and class constants had been accessible in TypeScript lengthy earlier than ECMAScript formally supported them.
Though TypeScript gives a number of benefits, it additionally brings some disadvantages. None of these disadvantages are deal-breakers, however a brand new developer wants to pay attention to them and take into account them.
One other drawback of TypeScript is the required further compilation step. This step can decelerate the construct time and complicate the bundler setup.
Since TypeScript provides many new options that may be unknown to a frontend developer, it will increase the educational curve of a codebase. Certainly, when used to its full potential, TypeScript might be difficult to know for untrained builders and requires a number of googling or mentorship from elder teammates.
Lastly, some builders complain that utilizing TypeScript requires including a number of further code to outline the kinds. Though true, this protects time in the long term as a result of it’s less complicated to onboard new challenge members. It additionally makes refactoring of the codebase simpler.
When Ought to You Use TypeScript for a New Mission?
Adopting a brand new expertise you haven’t had any expertise working with might be daunting. Nevertheless, with TypeScript, it’s well worth the shot, as a result of its benefits outweigh its disadvantages.
In the event you work on a challenge with teammates, the choice is extra complicated, as a result of it requires consent from the workforce and administration. Though, in the end, utilizing TypeScript will assist your workforce, it’s going to decelerate the event within the quick run. Additionally, the workforce must be ready to spend a while studying TypeScript, its options, and its best practices. That is the place having an skilled teammate with TypeScript or one other object-oriented programming language (equivalent to C#) will assist the workforce have a clean transition.
In case your workforce is ready to sacrifice short-term efficiency loss and preliminary time to be taught TypeScript, I like to recommend utilizing TypeScript in your challenge. You gained’t remorse it.
When Shouldn’t You Use TypeScript for a New Mission?
Even when TypeScript is mostly unbelievable, there are nonetheless explanation why I wouldn’t advocate utilizing it.
The most important purpose to not use TypeScript is in the event you or your workforce should respect a good deadline. Deadlines are anxious sufficient, and including a brand new expertise that you haven’t any expertise working with isn’t beneficial. Sadly, learning TypeScript takes time, and this time could also be higher spent elsewhere for initiatives with a deadline.
Additionally, TypeScript might be difficult to configure, particularly for newbies. It could require putting in a number of npm libraries and dealing with a bundler (like webpack). In the event you aren’t ready to spend the time studying all of this new info, don’t use it.
One other factor to think about is that utilizing TypeScript will enhance the builders’ entry threshold. If the challenge is open-source, this may enhance builders’ problem in contributing to it.
Additionally, for managers and hiring personnel, utilizing TypeScript in a challenge signifies that the builders you rent will need to have expertise utilizing TypeScript or one other OOP language. Adopting TypeScript raises the minimal job qualification to work on the challenge and may enhance the challenge’s funds, as a result of it is advisable rent extra skilled builders.
.ts, and fixing the errors outputted by the TypeScript compiler.
An alternative choice is to maintain the legacy code and solely write new options in TypeScript. When a function touches part of the legacy code, you’ll be able to migrate it concurrently whereas engaged on it.
Although it has just a few disadvantages, just like the code complexity that it provides or the added compile time, it’s going to prevent time in the long term.
In the event you work alone, I strongly encourage you to construct your subsequent software utilizing TypeScript.
In the event you work with a workforce, adopting TypeScript might require some convincing. I encourage you to start building a TypeScript project in your free time. You possibly can then present it to your teammates and clarify all of TypeScript’s benefits.
