# JavaScript: Clamp a number within the inclusive range specified by the given boundary values a and b

## JavaScript fundamental (ES6 Syntax): Exercise-266 with Solution

Write a JavaScript program to clamp a number within the inclusive range specified by the given boundary values a and b.

- If num falls within the range, return num.
- Otherwise, return the nearest number in the range.

**Sample Solution:**

**JavaScript Code:**

```
// Define a function 'clampNumber' to restrict a number within a specified range
const clampNumber = (num, a, b) =>
// Use Math.max and Math.min to ensure 'num' is within the range defined by 'a' and 'b'
Math.max(Math.min(num, Math.max(a, b)), Math.min(a, b));
// Test the function with different number and range combinations
console.log(clampNumber(2, 3, 5)); // Output: 3 (2 is clamped to the lower bound of the range)
console.log(clampNumber(1, -1, -5)); // Output: -1 (1 is clamped to the upper bound of the range)
```

Output:

3 -1
