Bài này mình sẽ cung cấp cho 248 một ví dụ về cách sử dụng Cách js với các ví dụ . Show Làm thế nào để js với các ví dụ /* JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. */ const array = [2, 5, 9];

alert('grepper!');Great choice for a great language. Have fun coding! Javascript is an interpreted, high level programming language developed and designed for web development. But now it is extensively being used in various fields rather than only web development after the development of node js. ________số 8 console.log("Hello, World!");

Bắt đầu các dự án của riêng bạn JS có dễ học không?JavaScript là ngôn ngữ lập trình đơn giản và dễ học so với các ngôn ngữ khác như C++, Ruby và Python. Đây là một ngôn ngữ thông dịch cấp cao, có thể dễ dàng được nhúng với các ngôn ngữ như HTML. JS có dễ hơn Python không?Mặc dù nhiều người nói Python dễ học hơn JavaScript, nhưng điều đó không đúng với những người có tư duy lập trình . Những điều cơ bản về JS có thể được học chỉ trong vài tháng và với một năm cống hiến, một người có thể bắt đầu kiếm được số tiền kha khá bằng kỹ năng của mình. JS có dễ hơn C không?Mặt khác, JavaScript được xây dựng ở mức trừu tượng cao hơn và có mục đích trở thành một ngôn ngữ dễ đọc hơn C++ đối với con người.
