JavaScript has dominated as the most-used programming language for years now.

How-does-a-JavaScript-runtime-environment-work

The runtime environment determines the global objects your JavaScript program will access and impacts how that program will run.

How does a JavaScript runtime environment work?

JavaScript is defined as an interpreted language.

Bun

JavaScript runtimes can be categorized into two: the runtime of a online window and a server-side JavaScript runtime.

This all-in-one runtime and toolkit has a test runner, bundler, and package manager compatible with Node.js.

Bun runs on Windows, Linux, and macOS.

Deno

Deno

Denois presented as a next-generation JavaScript runtime.

This tool is built on the V8 JavaScript engine and is backward compatible with npm and Node.js.

Deno is designed to support JavaScript extensions like JSX and TypeScript without extra configuration or build steps.

NodeJs

Node.js

Node.jsis a cross-platform, open-source JavaScript runtime environment.

This tool is designed to be performant as it is built on top of the V8 JavaScript engine.

Its standard library has a set of asynchronous I/O primitives that prevent JavaScript code from blocking.

Blueboat-1

Node.js is designed to handle multiple concurrent connections within a single server.

Blueboat

Blueboatis a serverless JavaScript runtime.

Blueboat works with most JavaScript/ TypeScript bundlers.

napajs-1

you’ve got the option to deploy a Blueboat project as a single-tenant or multi-tenant state.

Napa.js

Napa.jsis a multi-threaded JavaScript runtime.

However, this runtime has evolved and is now a good Node.js complement.

chakracore-1

Napa.js works perfectly on CPU-bound tasks as it can execute JavaScript in multiple V8 isolates and communicate between them.

The tool is presented as a Node.js module.

This engine runs perfectly on Windows, Linux, and macOS.

WasmEdge-2

The platform has several JSON-based diagnostic APIs.

These APIs are platform agonistic, and you might make them interoperable across different implementations.

The engine is based on a multi-tiered architecture.

tsnode-1

WasmEdge

WasmEdgeis an extensible, lightweight WebAssembly runtime for edge, cloud-native, and decentralized applications.

This runtime powers embedded functions, serverless apps, IoT devices, smart contracts, and microservices.

The platform offers a well-defined execution sandbox for the WebAssembly byte code program.

This software protects and isolates operating system resources like processes, environment variables, sockets, and file systems.

you might use WasmEdge with standard APIs and ES6 modules.

This runtime is also compatible with Node.js and NPM modules.

WasmEdge also allows developers to implement JavaScript APIs in Rust.

Ts-node

Ts-nodeis a REPL for Node.js and a TypeScript execution engine.

This tool allows developers to execute TypeScript on Node.js without going through the compilation phase.

Ts-node checks your node version and automatically provides defaults that match it.

Ts-node is designed to support a variety of options.

The tsconfig.json method is the most preferred.

JerryScript

JerryScriptis a lightweight JS engine that runs on constrained devices like microcontrollers.

The engine only has 64 KB RAM, and the ROM is constrained to 200 KB.

JerryScript supports on-gadget compilation and execution.

This engine also provides access to peripherals from JavaScript.

This engine offers various configuration options which you could use to turn specific features on/off.
