Detecting JavaScript Data Types: A Universal Method

The Challenge

Imagine a universe of data types in JavaScript! It's a colorful world with characters like Array, ArrayBuffer, Map, Set, Date, and the mysterious Function. Your mission, should you choose to accept it, is to create a universal method that identifies these inhabitants by their data type name.

Constraints:

The function should take only one argument—the data object.
We want a universal approach; using multiple if conditions to list and detect each data type is a no-go.

Example Usage

For the function detectType(), the following should hold true:

JAVASCRIPT

1detectType(1);           // Output: 'number'
2detectType(new Map());   // Output: 'map'
3detectType([]);          // Output: 'array'
4detectType(null);        // Output: 'null'

xxxxxxxxxx
 
function detectType(data) {
  return Object.prototype.toString
    .call(data)
    .slice(1, -1)
    .split(" ")[1]
    .toLowerCase();
}
​
