After a developer has created a function and has used types to define the number of variables the function can contain, TypeScript shows an error if someone else tries to increase the number of variables in the function.
Pros of Typescript
Static Typing System
In contrast, TypeScript provides static typing. With this, a variable assumes only one type and can only contain specific values. Static type gives the code a solid structure, so the code documents itself and is more readable. In addition, refactoring and debugging are faster, leading to fewer errors in code and better performance when executing code.
In this way, TypeScript helps you find a balance between flexibility and correctness, allowing you to change the level of type strictness at any part of the project.
TypeScript is predictable; every value stays the way it was defined. If a variable is defined as an object, it remains an object. As a result, everything works as intended.
Refactoring is a necessary aspect of codebase maintenance. It becomes a problem when refactoring is carried out and it affects the behavior of the updated app. With TypeScript, however, these issues are less likely to happen. The IDEs have studied your code and know how it functions, so navigation tools are made available for you. One example of these navigation tools is the "find all reference" tool (or go to definition).
In addition, TypeScript is fast at identifying mistakes (like changing the name of a function and forgetting to apply the change on all instances of the function being used). This is particularly beneficial when handling a large number of codebases.
TypeScript has a steadily growing community. It is used by big-shot companies like Microsoft and as well as designers of popular software packages like Slack. TypeScript is loved by many, and you can be sure to get assistance from the community.
Cross-platform and Cross-browser Compatibility
tsconfig.json to the correct root directory of a part of the codebase or the entire app.
Good IDE Support
Editors and Integrated Development Environments (IDEs) have improved functionality because with TypeScript, they have information about types. As a result, accurate suggestions and feedback are provided while you type your code. This gives you neater code, fewer errors, and increased productivity.
Supports Object-oriented Programming (OOP)
Class-based Object-oriented Programming (OOP) principles are supported by TypeScript. OOP helps to organize code as it grows.
Using strict types and other components makes codes self-expressive (syntactic sugar). Self-expressive code is readable, and the intent of the developer can be easily understood. This is particularly beneficial for projects between team members.
TypeScript allows team members to carry out their tasks without relying too much on each other. Dependency on team members can be a problem because it slows down progress and questions a programmer’s expertise.
TypeScript offers helpful pointers that help you solve your problems faster. Thanks to its self-expressive code, you can easily understand another developer's project.
In short, TypeScript increases the performance of individual developers and the entire team as a whole!
Identifies Bugs Early
According to researchers, TypeScript detects 15% of bugs at the compile stage. (Also, passing the code through a compiler reduces the amount of quality assurance and testing activities). Although it isn't much, this feature goes a long way because it allows developers to spend time correcting logic errors instead of finding common bugs.
Cons of Typescript
Although synthetic sugar and type annotations make code easier to read, they can cause other problems.
- The amount of code increases in TypeScript, and in turn, it can slow down the development process.
