Custom Add Function
The goal is to develop a customAdd()
function that performs addition or concatenation based on the input types provided. It should handle inputs intelligently, ensuring they are of the same type and managing special cases like booleans.
Functionality

Type Consistency: The function will check if the input arguments are of the same type. If not, it will raise an error.

Boolean Handling: When boolean values are passed as arguments, the function will convert them to numbers before performing addition.

String Concatenation: If both arguments are strings, the function will concatenate them instead of performing mathematical addition.
Expected Outcomes

Identical Types: If
a
andb
are of the same type (and not booleans),customAdd(a, b)
will return their sum or concatenation. 
Type Mismatch: If
a
andb
are of different types,customAdd(a, b)
will throw an error with the textArguments should be of the same type

Boolean Inputs: If
a
andb
are booleans,customAdd(a, b)
will convert them to numbers and return their sum.
By following these instructions, the customAdd()
function will be robust and versatile, capable of handling various input types appropriately.
Make sure to export the
customAdd()
function using ESM syntax to make it available for the tests
