JavaScript: Limit a value inside a certain range

JavaScript Math: Exercise-37 with Solution

Write a JavaScript function to limit a value inside a certain range.

Note : If the value is higher than max it will return max. and if the value is smaller than min it will return the min.
Test Data :
console.log(value_limit(7, 1, 12));
7
console.log(value_limit(-7, 0, 12));
0
console.log(value_limit(15, 0, 12));
12

Sample Solution:

JavaScript Code:

// Define a function named value_limit that restricts a value within a specified range.
function value_limit(val, min, max) {
  // If val is less than min, return min; otherwise, if val is greater than max, return max; otherwise, return val.
  return val < min ? min : (val > max ? max : val);
}

// Output the result of restricting the value 7 within the range [1, 12] to the console.
console.log(value_limit(7, 1, 12));
// Output the result of restricting the value -7 within the range [0, 12] to the console.
console.log(value_limit(-7, 0, 12));
// Output the result of restricting the value 15 within the range [0, 12] to the console.
console.log(value_limit(15, 0, 12));

Output:

7
0
12
