Gets the command-line arguments passed to a Node.js script.
|
|
|
|
- Use `process.argv` to get an array of all command-line arguments.
|
|
- Use `Array.prototype.slice()` to remove the first two elements (path of the Node.js executable and the file being executed).
|
|
|
|
```js
|
|
const getCmdArgs = () => process.argv.slice(2);
|
|
```
|
|
|
|
```js
|
|
// node my-script.js --name=John --age=30
|
|
getCmdArgs(); // ['--name=John', '--age=30']
|
|
```
