Return Length of Arguments Passed

Problem Statement

The task is to implement a function named argumentsLength which computes and returns the number of arguments it receives. This function should be able to handle any arbitrary number of inputs, from zero to a maximum of 100 arguments. The inputs could be of any type including numbers, objects, strings, etc., fitting within a JSON format.

Examples

Example 1

Input:

args = [5]

Output:

1

Explanation:

argumentsLength(5); // 1
One value was passed to the function so it should return 1.

Example 2

Input:

args = [{}, null, "3"]

Output:

3

Explanation:

argumentsLength({}, null, "3"); // 3
Three values were passed to the function so it should return 3.

Constraints

• args is a valid JSON array
• 0 <= args.length <= 100

Approach and Intuition

To solve this problem, one should construct the function to accept varying arguments, possibly leveraging the JavaScript rest parameters syntax for simplicity. The function should account for diverse input types as well as varying numbers of inputs conveyed by the constraints.

1. Function Definition: Define the function such that it takes advantage of JavaScript's flexible handling of arguments using rest parameters. This should allow the function to capture any number of inputs passed to it efficiently and dynamically.

2. Counting Arguments: Inside the function, the length property of the arguments array-like object (or the rest parameter which is an actual array) can be used to determine the number of items passed to the function.

3. Return Value: The counted value, which represents the number of arguments passed, will then be returned as the output of the function.

Considering Input Types and Constraints:

• The function needs to be capable of handling various input types such as integers, strings, objects, and other valid JSON values.
• Given the array constraint, even though we use rest parameters, the concept of input remains compliant with said constraint since an array can be conceptually mapped to the function's arguments.
• The numerical constraint ensures that at most 100 items can be processed, reducing concerns about excessive compute times or resource usage.

With these steps clearly defined and the constraints properly accounted for, the argumentsLength function will robustly return the correct count of arguments provided within the specified limits.

Solutions

var countArgs = function(...params) {
    return params.length
};
