# Simple usage
## 1. Logging PowerShell version
This example is the most popular thing that people love about using **PowerShell**
{% code title="simple-example.js" %}
```javascript
// Print PowerShell Version using PowerJS
import { PowerJS } from "@obayd/powerjs";
const instance = new PowerJS(/* options */);
instance.exec("$PSVersionTable").then((result) => {
// You may notice some slowdown, that's because of the instance init process.
// After the instance is started, you can enjoy a blazing fast environnement!
console.log("Currently on Powershell v" + result.PSVersion.Major + "!");
});
```
{% endcode %}
#### PowerShell Version Table:
Try executing `$PSVersionTable` and `$PSVersionTable.PSVersion` in a **PowerShell** terminal.
Execution result
You should see something simillar to the above.
**PowerJS** behind the scenes try to transport data between **PowerShell** and your **Node** Process
When running the example code, you should see:
Execution result
However, the `7` there is the same as `$PSVersionTable.PSVersion.Major`, that means it can differ in your side.
#### **In step-by-step:**
1. Import **PowerJS** library using the `import` statement. Currently **PowerJS** exports many things, so you will need to destructure[^1] imported object using `{...}` ,and get only `PowerJS` object
2. Create an instance using the new operator.
3. Execute `$PSVersionTable` to get A *version table* object [#powershell-version-table](#powershell-version-table "mention"), then wait for response.
4. Extract the Major part of the version, using `result.PSVersion.Major`.
## 2. Logging User names
This task is common when it comes to automation and system management
{% code title="super-simple-example.js" %}
```javascript
// Read the local user list
import { PowerJS } from "@obayd/powerjs";
const instance = new PowerJS();
instance.exec(",(Get-LocalUser)").then(function (result) {
// Use the , to make arrays returnable, otherwise, it will return only the first item
// Read https://stackoverflow.com/questions/29973212/pipe-complete-array-objects-instead-of-array-items-one-at-a-time
for (const user of result) {
console.log(user.Name);
}
process.exit();
});
```
{% endcode %}
