WebAssembly vs. JavaScript: Why WebAssembly is Better?
WebAssembly (abbreviated as Wasm) is a new web technology that has gained a lot of attention recently. It provides an efficient and fast execution environment that can replace traditional JavaScript in many applications. Why is WebAssembly a better choice compared to JavaScript?
Differences in Execution Speed Favoring WebAssembly
One of the most significant differences between WebAssembly and JavaScript is execution speed. JavaScript is an interpreted language, meaning the browser executes the code line by line. This can slow down execution time, especially in resource-efficient applications. On the other hand, WebAssembly is binary code that can be executed directly in machine language, making it much faster than JavaScript.
WebAssembly’s execution speed is particularly notable when dealing with computationally intensive tasks such as 3D graphics or image processing. It can perform these tasks even tens of times faster than JavaScript. WebAssembly significantly accelerates applications running in the browser.
Javascript is considerably larger and slower than WebAssembly
Another significant difference between WebAssembly and JavaScript is size. JavaScript files can be quite large, which can slow down load times and increase network traffic. In contrast, WebAssembly’s binary files are much smaller, resulting in faster loading and less network usage.
The smaller size makes WebAssembly an ideal choice for mobile applications where data transfer speed may be limited. It also helps improve the user experience because applications load faster and operate more smoothly.
WebAssembly offers several advantages over traditional JavaScript. It is faster, smaller, and provides a more efficient execution environment. While JavaScript remains a crucial part of web development, WebAssembly offers a new alternative that can enhance performance and user experience in many applications.
