![]() ![]() Let's compare creating an element using JavaScript and JSX. JSX allows you to write more concise and cleaner code, making it easier to understand and maintain. The answer lies in the readability and ease of use that JSX brings to the table. You might be wondering why we need JSX when we can use JavaScript to create and manipulate HTML elements. Luckily, this is done automatically when you use tools like Babel, which is commonly used with React. It needs to be compiled down to plain JavaScript in order to work. One thing to note is that JSX is not natively understood by web browsers. Think of it as a way to mix JavaScript and HTML together in a more natural and intuitive way. JSX is not a new language or a templating engine but a way to write markup and code together within a single file. It is a syntax extension for JavaScript that allows you to write HTML-like code within your JavaScript code. We will also see some code examples to better understand its usage. In this article, we will learn what JSX is, how it works, and how to use it in a React application. One of the unique features of React is JSX. It allows developers to create reusable components that can be easily manipulated and rendered on a web page. | expr '.React is a popular JavaScript library for building user interfaces. The BNF-like grammar for amp-bind expressions: To make this work, you need to enable the development mode. Use AMP.printState() to print the current state to the console. amp-bind delegates expensive work to a dedicated Web Worker to ensure good performance.

Errorsīelow outlines the types of errors that may arise when working with amp-bind. A property is bound by wrapping it inside brackets, in the form of. Bindings: Special attributes that link an element's property to a state via an expression.Expressions: JavaScript-like expressions that can reference the state.Visual elements should have their default "state" defined and not rely amp-bind for initial render. amp-bind does not evaluate expressions on page load. State variables update in response to user actions. State: A document-scope, mutable JSON state.Watch this video for an introduction to amp-bind. This means visual elements should be given a default state and not rely on amp-bind for initial render. The amp-bind component enables custom stateful interactivity on AMP pages.įor performance, and to avoid the risk of unexpected content jumping, amp-bind does not evaluate expressions on page load. ![]() Amp-autocomplete amp-bind-macro amp-bind-recaptcha amp-bind amp-date-picker amp-geo amp-iframe amp-img amp-lightbox amp-list amp-selector AMP for E-Commerce Getting Started Product Browse Page Product Page Client-side filtering Conditional State Copy Button Currency Conversion Dynamic Accordion Dynamic Content After User-Interaction Linked Dropdowns Multi Page Flow Restrict Duplicate Selection Show More Button Tic-Tac-Toe Image Galleries with amp-carousel Animated Snackbar amp-analytics Checkout Flow Hotel Shopping Cart Favorite Button Paged List SeatMap SeatMap Multiple Selection Usage
