How to use javascript on Apple computers

We know that JavaScript is a widely used application language that can achieve interactive and dynamic effects in web pages. For users of Apple computers, how to run and use JavaScript on their computers? This article will introduce step by step how to use JavaScript on Apple computers.

Step One: Preparation

First, we need to install a code editor to write JavaScript code. The TextEdit that comes with Apple computers is not suitable for writing code. We need to download an editor suitable for programming. Common editors include Visual Studio Code, Sublime Text, Atom, etc. You can choose the appropriate editor according to your needs.

Secondly, we need to install Node.js on the Apple computer. Node.js is a JavaScript running environment based on the Chrome V8 engine, which allows JavaScript to run on the server side. To install Node.js, you can download the installation package from the official website, or use the package manager Homebrew to install it.

Step 2: Write JavaScript code

Open the editor and create a new js file. Enter the following code:

console.log("Hello, world!");

Save the file and name it "hello.js".

Step 3: Run the JavaScript code

In the terminal, enter the path where the file is located and enter the following command:

node hello.js

Press Enter to view it in the terminal The output result is "Hello, world!". This means that we successfully used JavaScript on Apple computers.

In addition to running JavaScript code in the terminal, we can also achieve dynamic interactive effects by embedding JavaScript code in web pages. Both the Safari browser and the Chrome browser that come with Apple computers support JavaScript. We can use JavaScript in web pages to dynamically change web page content or implement other functions.

Step 4: Learn JavaScript knowledge

If you want to learn JavaScript in depth, we recommend some excellent learning resources:

• Ruan Yifeng’s blog: Teacher Ruan Yifeng He is a well-known JavaScript tutorial blogger in China. His blog has a large number of in-depth and simple JavaScript tutorials, including ES6 new features, closures, scopes, etc.
• MDN Web Docs: MDN Web Docs is an authoritative web development documentation website, including JavaScript knowledge points, APIs and other content.
• freeCodeCamp: freeCodeCamp is a free project-driven programming course that provides a series of JavaScript courses and project exercises, suitable for beginners and advanced people.

Summary

Using JavaScript allows us to achieve interactive effects in web pages and improve user experience. Using JavaScript on Apple computers requires the installation of a code editor and the Node.js operating environment. The effect can also be achieved by embedding JavaScript code in web pages. If you want to learn JavaScript in depth, you can refer to the learning resources recommended above.
