Svelte.js: The New Tool on the Block in the World of JavaScript Frameworks
Hello HaWkers! Today, we're going to explore a new JavaScript framework that's catching the attention of web developers for its innovative and efficient approach to building user interfaces - Svelte.js.
What is Svelte.js?
Svelte is a modern JavaScript framework for building user interfaces. What sets it apart from other frameworks like React and Vue is that Svelte does most of the heavy lifting during the compilation phase rather than at runtime. This results in more efficient code that can improve your application's performance.
How does Svelte.js work?
Instead of using a virtual machine like React to interpret the application code in real time, Svelte converts the application to optimal JavaScript code during compilation. This means the browser has much less work to do, resulting in faster performance.
Let's go to the code
Let's create a simple component in Svelte. First, create a new file with the extension .svelte. Let's call it HelloWorld.svelte.
<script> let name = 'world';</script><h1>Hello {name}!</h1><input bind:value={name}>Here we create a Svelte component that renders a header and input field. The input field value is linked to the name variable, so any change to the input field will update the header in real time.
Conclusion
Svelte.js is an exciting addition to the world of JavaScript frameworks. Its unique approach to compiling JavaScript code can bring significant benefits in terms of performance and efficiency.
