How to use javascript on Apple computers

With the rapid development of technology, people are becoming more and more dependent on technology. Especially in the field of computers, various operating systems, languages, and software emerge in endlessly, the most representative of which is Apple's macOS system. In this system, JavaScript is also an indispensable programming language. This article will introduce how to use JavaScript on Apple computers.

1. Prerequisites

Before using JavaScript, you must first confirm whether the JavaScript engine has been installed on your Apple computer. In macOS, the JavaScript engine is shared by the Safari browser and several other Apple software. Therefore, if you have installed Safari or other Apple software, you do not need to install the JavaScript engine separately.

2. Create a JavaScript program

To write a JavaScript program on an Apple computer, you can use TextEdit (text editor) or other text editors. After opening TextEdit, you can press the shortcut key "Command N" to create a new text file.

When writing and saving a JavaScript program in a text file, you need to pay attention to the following points:

1. File name: The file name of the JavaScript program must end with ".js", such as " example.js".
2. Save type: When saving the file, you need to select the "Plain Text" format instead of the "Rich Text" format. This ensures that JavaScript programs can run properly.

3. Run JavaScript program

1. Use Safari browser to execute JavaScript program

Safari browser is the default browser for Apple computers. It is also a JavaScript interpreter. You can use the Safari browser to execute a JavaScript program through the following steps:

① Write the JavaScript program in TextEdit and save the file in ".js" format.

② Open the Safari browser and enter the "file:///" file path in the address bar to open the JavaScript program. For example, if the file path is "/Users/yourname/Desktop/example.js", enter "file:///Users/yourname/Desktop/example.js" in the address bar.

③ Press the "Enter" key to see the running results of the JavaScript program.

2. Use Node.js to execute JavaScript programs

Node.js is a JavaScript running environment based on the Chrome V8 engine. It can run JavaScript programs independently on Apple computers without the need for a browser.

You can use Node.js to execute JavaScript programs through the following steps:

① First, you need to install Node.js in Terminal. After opening Terminal, enter the following command:

brew install node

The terminal will automatically download and install Node.js.

② Write the JavaScript program in TextEdit and save the file in ".js" format.

③ Enter the folder where the JavaScript program is saved in Terminal and enter the following command to run the JavaScript program:

node example.js

example.js is the file name of the JavaScript program.

You can successfully run the JavaScript program through the above steps.

4. Summary

Through the above steps, we can successfully execute JavaScript programs on Apple computers. Of course, JavaScript is a very powerful programming language. Understanding more features of JavaScript can expand more unique applications. Hope this article will be helpful to you.
