JavaScript vs WebAssembly

Use JavaScript when developing web applications that require client-side interactivity, such as real-time updates or form validation, or when using Node meets developers should learn webassembly when building performance-critical web applications, such as games, video editing tools, or scientific simulations, where javascript may be too slow. Here's our take.

JavaScript

Nice Pick

Use JavaScript when developing web applications that require client-side interactivity, such as real-time updates or form validation, or when using Node

Pros

• js for server-side development with high concurrency needs, as seen in chat applications or APIs
• Related to: react, vue

Cons

• Specific tradeoffs depend on your use case

WebAssembly

Developers should learn WebAssembly when building performance-critical web applications, such as games, video editing tools, or scientific simulations, where JavaScript may be too slow

Pros

• It's also useful for porting existing codebases from languages like C++ to the web without rewriting them in JavaScript
• Related to: javascript, rust

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. JavaScript is a language while WebAssembly is a platform. We picked JavaScript based on overall popularity, but your choice depends on what you're building.

The Bottom Line

JavaScript wins

Based on overall popularity. JavaScript is more widely used, but WebAssembly excels in its own space.
