Improve type checking by using type annotations: Type annotations are opportunistic type statements that inform TypeScript about the appropriate type value for a variable, method, or property. They help TypeScript identify type-related problems at compile time and prevent them from occurring at run time.
Use interfaces to define reusable types: It’s easy to construct reusable types that can be used in different parts of your code, thanks to interfaces that offer an object plan.
Use type inference: TypeScript has a feature called type inference that allows it to automatically determine the type of a value based on its usage. As a result, your code can be greatly simplified and you’ll have to write fewer type annotations.
Utilize generics for more adaptable code: You can create code using generics that can operate on any type of value. Your code may become more adaptable and reusable as a result.
Learn about the more sophisticated TypeScript features: Decorators, enums, and namespaces are just a few of the sophisticated features of TypeScript that may help you organise and structure your code much better.
Use the function’s default values for the parameters: You can define a default value for a parameter using default values for function parameters in the event that no value is passed to the function. This can make your code more flexible and help prevent problems.
Use classes for object-oriented programming: TypeScript provides support for classes, a key component of OO development. They offer a practical mechanism for producing objects with particular attributes and capabilities.
Keep your code well-documented: TypeScript supports JSDoc-style comments, which is important for any codebase. All of your code, including types and interfaces, must have thorough and succinct documentation.
Understand the differences between let and const: TypeScript uses these two keywords to declare variables. Const is used to declare a constant that cannot be reassigned, whereas let is used to declare a variable that can.
Use destructuring for easier data access: Destructuring is a feature in TypeScript that allows you to extract values from arrays or objects and assign them to individual variables. It makes it easier to access and manipulate data within your code.
