This Just enter a separate js code at the cursor, as shown below, I randomly executed some javascript code

[It should be noted that I heard that the way to enter the node mode to execute js code is only one line Execute js code line by line, but cannot execute a js file】

2. Use node to execute the entire js script file

If If you want to use node to directly execute an entire nodejs file, you cannot enter the editing mode of node. Instead, you should enter directly in the command box: node js file name

is as follows:

node hello
或者
node hello.js

For the js file following node, the .js suffix can be added or not. (Note: If the js file is not in the directory where the current command box is located, you need to locate the command box in the corresponding directory first, or add the specific path of the js file name after node)
