What does the Join words() function do?

1. Separates two strings

2. Concatenates two values

3. Calculates the length of a string

4. Reverses a string

The correct answer is: Concatenates two values

The Join words() function is designed to concatenate two or more strings or values into a single string. This function typically takes a collection of words or strings as input and combines them, usually with a specified delimiter between each value, effectively serving to create a single cohesive sequence from multiple components. In the context of this function, concatenation means linking items together in a sequence, which is essential in a variety of applications such as formatting output, constructing sentences, or processing data where multiple inputs need to be combined into one. Understanding how this function operates is crucial as it highlights the fundamental concept of combining data, which is a common operation in programming and data manipulation.
