Browsers
JavaScript was created to run in browsers, making browser compatibility essential for developers. Here are the main browsers to consider:
- IE 6~11: Widely used in China but historically has poor support for W3C standards. ES6 support starts from IE10.
- Chrome: Developed by Google and based on the Webkit engine, it features the powerful V8 JavaScript engine. Chrome auto-updates, ensuring the latest version always supports ES6.
- Safari: Apple's default browser on macOS, based on Webkit. It began supporting ES6 from version 6.1, included in OS X 10.7 Lion. The latest versions, such as Safari 9.x in OS X 10.11 El Capitan, fully support ES6.
- Firefox: Developed by Mozilla with its Gecko engine and OdinMonkey for JavaScript. Firefox has transitioned to auto-updating, similar to Chrome, to stay current.
- Mobile Browsers: iOS primarily uses Safari, while Android mainly uses Chrome. Both support HTML5 and ES6 well due to their Webkit foundation.
Be cautious of domestic browsers like certain security or dual-core browsers, which may run on IE or a hybrid of engines.
Different browsers can have varying support for JavaScript APIs (e.g., AJAX, File interface) and ES6 features. When writing JavaScript, aim for cross-browser compatibility to ensure consistent functionality across different platforms.
