 ### Color the output
 
-You can color the output of your text in the console by using [escape sequences](https://gist.github.com/iamnewton/8754917). An escape sequence is a set of characters that identifies a color.
-
-Example:
-
-```js
-console.log('\x1b[33m%s\x1b[0m', 'hi!');
-```
-
-You can try that in the Node.js REPL, and it will print `hi!` in yellow.
+> **NOTE**
+> This part of the resource is designed with version 22.11 which notes `styleText` as ‘Active development’.
 
-However, this is the low-level way to do this. The simplest way to go about coloring the console output is by using a library. [Chalk](https://github.com/chalk/chalk) is such a library, and in addition to coloring it also helps with other styling facilities, like making text bold, italic or underlined.
+In many cases, you will be tempted to paste certain text to get a nice output at the terminal.
 
-You install it with `npm install chalk`, then you can use it:
+There is a `styleText` function provided by the `node:util` module. Let's discover how to use it.
 
-```js
-const chalk = require('chalk');
+First of all, you need to import the `styleText` function from the `node:util` module:
 
-console.log(chalk.yellow('hi!'));
+```mjs
+import { styleText } from 'node:util';
 ```
 
-Using `chalk.yellow` is much more convenient than trying to remember the escape codes, and the code is much more readable.

-Check the project link posted above for more usage examples.

-  if (bar.complete) {
-    clearInterval(timer);
-  }
-}, 100);
+console.log(
+  styleText(['red'], 'This is red text ') +
+    styleText(['green, bold'], 'and this is green bold text ') +
+    'this is normal text'
+);
 ```

+The first argument is an array of styles, and the second argument is the text you want to style. We invite you to read [the docs](https://nodejs.org/docs/latest-v22.x/api/util.html#utilstyletextformat-text-options)

+
+## Run a task with Node.js
+
+Node.js provides a built-in task runner that allows you to execute specific commands defined in your `package.json` file. This can be particularly useful for automating repetitive tasks such as running tests, building your project, or linting your code.
+
+### Using the `--run` flag
+
+The [`--run`](https://nodejs.org/docs/latest-v22.x/api/cli.html#--run) flag allows you to run a specified command from the `scripts` section of your `package.json` file. For example, if you have the following `package.json`:
+
+```json
+{
+  "type": "module",
+  "scripts": {
+    "start": "node app.js",
+    "dev": "node --run -- --watch",
+    "test": "node --test"
+  }
+}
+```
+
+You can run the `test` script using the `--run` flag:
+
+```bash
+node --run test
+```
+
+### Passing arguments to the command
+
+Let's explain the `dev` key in the `scripts` object of the `package.json` file.
+
+The syntax `-- --another-argument` is used to pass arguments to the command. In this case, the `--watch` argument is passed to the `dev` script.
+
+```bash
+node --run dev
+```
+
+### Environment variables
+
+The `--run` flag sets specific environment variables that can be useful for your scripts:
+
+- `NODE_RUN_SCRIPT_NAME`: The name of the script being run.
+- `NODE_RUN_PACKAGE_JSON_PATH`: The path to the `package.json` file being processed.
+
+### Intentional limitations
+
+The Node.js task runner is intentionally more limited compared to other task runners like `npm run` or `yarn run`. It focuses on performance and simplicity, omitting features like running `pre` or `post` scripts. This makes it suitable for straightforward tasks but may not cover all use cases.
