Best Trending similar Alternatives for JavaScript and its uses

Before mentioning the alternatives for js and it uses, JavaScript is one of the easiest, versatile and effective languages used to extend functionality in websites. JavaScript Development Services helps in on-screen visual effects and processing and calculating data on web pages with ease. The programming language also helps in extended functionality to websites using third party scripts among several other handy features. But People’s choices are different to each other. So let’s get to the trending technologies if you are not comfortable with using js.

Before that let’s see why some people hate js.

It was supposed to be a simple, quick, easy to understand scripting language for the web. It was supposed to be a tool that would help you in writing your web sites. Maybe you had to do a dynamic loop instead of writing something multiple times, or maybe you wanted to have a special case for pressing certain hotkeys. Some behaviors of the language are a reflection of this: you rarely have any errors until they absolutely have to happen (rather than early/pre-runtime errors of C compilers), for example, non-strict mode exists, etc.

The first thing that must not be neglected when developing a web application is performance. Now, JavaScript limitations make heavy calculations slow. That significantly worsen the user experience.

JavaScript has faults. Other answers go into great detail about them, exaggerating many of them to the extreme, so I won’t bother with them here. It was designed quickly for marketing reasons (so they could say “we have a script language in the browser!”).

And you can always choose different Programing language for your developing purposes like java, c#, etc… but some of the features offered by js and from its frameworks, cannot be obtain by any other programing language or their frameworks. So that’s why we should look for alternatives similar to js.

Why JavaScript Deserves More Love Than Hate

Let’s see what are the alternatives that we are going explore

Typescript

We have languages that compiles into JavaScript, like Coffeescript or TypeScript

What is Typescript?

Typescript is a modern age Javascript development language. It is a statically compiled language to write clear and simple Javascript code. It can be run on Node js or any browser which supports ECMAScript 3 or newer versions.

Typescript provides optional static typing, classes, and interface. For a large JavaScript project adopting Typescript can bring you more robust software and easily deployable with a regular JavaScript application.

Still TypeScript is just a superset of JavaScript

KEY DIFFERENCE

• JavaScript is a scripting language which helps you create interactive web pages whereas Typescript is a superset of JavaScript.
• Typescript code needs to be compiled while JavaScript code doesn’t need to compile.
• Typescript supports a feature of prototyping while JavaScript doesn’t support this feature.
• Typescript uses concepts like types and interfaces to describe data being used whereas JavaScript has no such concept.
• Typescript is a powerful type system, including generics & JS features for large size project whereas JavaScript is an ideal option for small size project.

WebAssembly

Now, JavaScript limitations make heavy calculations slow. That significantly worsen the user experience.

This is one of the main reasons for the rising popularity of WebAssembly. With this technology, the code in any programming language can be compiled into bytecode, which runs in a browser.

WebAssembly is an open standard that defines a portable binary-code format for executable programs, and a corresponding textual assembly language, as well as interfaces for facilitating interactions between such programs and their host environment.

Advantages:

• It’s independent of programming language and platform
• Independent of hardware
• Executes code fast
• Provides a high level of security.

It all comes down to the triangle — small footprint, cross-platform scripting, and speed. All three of these components are the key ones in modern web development. This is why a lion’s share of web development cases is not without WebAssembly today.

Angular 2

When it comes to choose frontend framework you can always choose Angular 2 because its use typescript

Angular is a TypeScript-based open-source web application framework led by the Angular Team at Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.

One vital distinction between Angular vs AngularJS is AngularJS is JavaScript-based while Angular is TypeScript based. These two frameworks have similarities as a front end, open-source platform that create dynamic SPAs

Additional Information- Now other popular frontend frameworks like ReactJs and VueJs also supported to typescript

Deno

First of all, Deno is not a fork of Node — it’s a new implementation based on modern features of the JavaScript language, although the name is an anagram of Node. Deno is a secure runtime for JavaScript and TypeScript based on Google’s V8 and its core is built in Rust (Node’s implementation is in C++). It uses Tokio for its event loop, which is also written in Rust.

Deno ships as a single executable with no dependencies and comes with some built-in tools to make the developer experience easier:

Deno is based on TypeScript, so it supports it out of the box without the need to install or configure tools, like adding a tsconfig.json configuration file in Node. Although it comes with a default config file, it's possible to add your own

NestJs

When developers want more less complex backend framework, they mostly choose expressJs but most of the time when people hate js they go ahead and hate expressJs.

If there is a question in your mind that which is the best framework, either Nestjs or Express then there are some key points you have to check, before going to make any judgement.

Express is better to use for solving problems kind of routing, body parsing, etc.

NestJS is quite good to structure your code in a better-organized way, it allows you to write clearer, reusable code with higher-level constructs like filters, pipes, interceptors, etc.

However NestJS uses the Express middleware.

For beginners, NestJS seems to be complicated a little bit, which for a simple app would not be needed. However, as you can scale your application and would love for the way how NestJS organizes the code.

NestJS is a progressive Node.js framework for building efficient and scalable server-side applications.

It uses progressive JavaScript built with Type JavaScript and adds elements of object-oriented programming, functional programming, functional reactive programming under the hood. NestJS uses Express but also provides compatibility with a wide range of other libraries, such as. Fastify, TypeORM, etc.

On the other hand, Node.js is a platform built on Chrome’s JavaScript runtime to build easily fast, scalable network applications and uses an event-driven, non-blocking I / O model that makes it data- Makes it perfect and lightweight for Intensive. Real-time applications that run in distributed devices.

After considering some these alternative choices you can see Typescript has become a solution to some of JavaScript issues that developers are having. But still some of issues are not avoidable as well as we cannot ignore the unique features provided by JavaScript.
