Correcting Issues when Adding a Between Method to the Number Prototype

32 views

It looks like you are trying to extend the Number prototype by adding a between method, which checks if a number is within a specified range. However, the way it is written has a few issues.

Here is a corrected version:

Number.prototype.between = function(min, max) {
  return this >= min && this <= max;
};

// Example usage
let response = { statusCode: 200 };

console.log(response.statusCode.between(200, 299)); // true

If you save the above code in a JavaScript file and run it, it will correctly check if response.statusCode is between 200 and 299.

Explanation:

  1. Number.prototype.between = function(min, max) {...}: This properly extends the Number prototype with a method named between. Note that it uses a regular function (function(min, max)) rather than an arrow function.

  2. return this >= min && this <= max;: The function checks if this (the number it is called on) is greater than or equal to min and less than or equal to max.

  3. let response = { statusCode: 200 };: This is an example object with a statusCode property set to 200.

  4. console.log(response.statusCode.between(200, 299));: This line uses the between method to check if response.statusCode is within the range 200 to 299 and logs true to the console.

Feel free to copy and use this code as needed!
