How to enable javascript

JavaScript is a popular programming language that is widely used in front-end development and can realize interactive effects on web pages, such as form validation, pop-up boxes, carousels, etc. For anyone who wants to learn JavaScript or want to use it on their own website, enabling JavaScript is a necessary step.
