You can find the square root of a number in JavaScript using the **Math.sqrt()** function. Here's a simple example:

```plaintext
// Function to find the square root of a number
function findSquareRoot(number) {
  // Check if the number is non-negative
  if (number >= 0) {
    // Use Math.sqrt() to calculate the square root
    return Math.sqrt(number);
  } else {
    // If the number is negative, return NaN (Not a Number)
    return NaN;
  }
}

// Example usage
let numToFindSquareRoot = 25;
let result = findSquareRoot(numToFindSquareRoot);

if (!isNaN(result)) {
  console.log(`The square root of ${numToFindSquareRoot} is: ${result}`);
} else {
  console.log(`Cannot calculate the square root of a negative number.`);
}
```

In this example, the **findSquareRoot** function takes a number as an argument, checks if it's non-negative, and then uses **Math.sqrt()** to calculate the square root. If the number is negative, it returns **NaN** (Not a Number).

You can change the value of **numToFindSquareRoot** to find the square root of different numbers. Note that the result will be a floating-point number, even if the input is an integer.
