The given code is written in JavaScript.

Step 1: Import the crypto module using the require() function.
```javascript
const crypto = require('crypto');
```

Step 2: Define a secret key for the HMAC algorithm.
```javascript
const secret = 'abcdefg';
```

Step 3: Create an HMAC object using the createHmac() method from the crypto module. Pass the algorithm (in this case, 'sha256') and the secret key as parameters.
```javascript
const hash = crypto.createHmac('sha256', secret)
```

Step 4: Update the HMAC object with the data to be hashed. In this case, the string 'Welcome to JavaTpoint' is used.
```javascript
.update('Welcome to JavaTpoint')
```

Step 5: Generate the hash value by calling the digest() method with the 'hex' encoding.
```javascript
.digest('hex');
```

Step 6: Print the hash value to the console.
```javascript
console.log(hash);
```

The output will be the hash value of the given data using the HMAC algorithm with the SHA-256 hash function.
