JavaScript & TypeScript
As time goes on, the web age changes, and new tools and architectures are made to deal with problems that are unique to older systems. TypeScript is part of this change, but what is it exactly?
JavaScript is one of the most used programming languages for both the client and the server. If you’ve ever worked on a project that used JavaScript, you already know how it works. But we will talk more about TypeScript, which is an alternative programming language to JavaScript. We will talk about its features and benefits.
When using JavaScript, you can declare a variable as a string and then later reassign the same variable as an integer. But it can’t do everything. Changing the data type of a variable can cause your performance to vary.
Microsoft has made TypeScript, a new JavaScript language. It was made to be better than JavaScript. It uses the same syntax and has all of the new features that ES6 (ECMAScript programming language version 6) supports, as well as classes. TypeScript adds features like type-inference, generics, private class members, and inheritance that make JavaScript’s built-in object-oriented features better.
TypeScript’s Features:
TypeScript, a fast JavaScript alternative, is vital for building massive code base applications. Angular uses TypeScript. Master these features to make your codebase more robust, cleaner, and easier.
- Inference
TypeScript determines the variable’s data type based on its initial value. It is a major time-saver because you do not have to explicitly specify the data type for all variables. Number, Boolean, and string are primitive type annotations. Array, enum, and void annotations help TypeScript data types.
- Typecheck
Typescript detects various problems during runtime. In large projects with numerous developers, a change in one portion of the code affects the complete codebase. TypeScript saves developers time and hassle by verifying that their code will compile.
- OOP (OOP)
Object-oriented languages help us maintain a clean, stable codebase. In addition, TypeScript aids OOP with easy-to-use classes, interfaces, and modules in a more elegant style in comparison to JavaScript interfaces.
TypeScript classes, interfaces, and modules work well. Client-aspect and server-aspect development can use natural object-oriented programming. It outshines JavaScript. OOP functions also structure TypeScript code.
- Generics
This feature allows flexible coding for several data types. Users can write data types. This feature is common in programming languages, but to use Generic with TypeScript, one must write a type parameter “T” (can be named differently because T is a placeholder) inside the open < and close > bracket and a specify type function removeFirstEntryFromArray() must precede to know the user’s type.
Support ES6
ES6 supersedes TypeScript. It has all ES6 features and more. Lambda functions are examples. Anonymous capabilities (classes, interfaces, arrow capabilities, etc.) in ES6 offer a modest alternative.
- Compatibilities
JavaScript matches TypeScript tasks. TypeScript is a strict superset of ECMAScript 2015, which is a superset of JavaScript, ECMAScript 5. Thus, TypeScript program can easily consume JavaScript. The compiler targets ECMAScript 5, the current standard, but can also generate constructs for ECMAScript 3 or 2015.
TypeScript makes it easier to reuse JavaScript code, include popular libraries, and call TypeScript-generated code from other JavaScript. The provided code includes library type declarations.
