Refer to the code below: const pi = 3.1415926; What is the data type of pi?

JavaScript has only one type for all numbers, both integers and floating-point values. This type is called Number. It is based on the IEEE 754 double-precision 64-bit binary format. While the value 3.1415926 is a floating-point number conceptually, its data type in JavaScript is simply Number. The language does not have distinct Float, Double, or Decimal primitive types.

B. Float is not a primitive data type in JavaScript. It's a concept used in other languages like Java or C++.

C. Double is not a primitive data type in JavaScript, although the Number type is implemented as a double-precision float.

D. Decimal is not a primitive data type in JavaScript. High-precision decimals require libraries like Decimal.js.
