Question

what does concatenation mean?

Answer 1

Concatenation refers to the process of linking or joining two or more things together in a series. In computer science and programming, it often specifically refers to combining strings of text. For example, if you have two strings, "Hello" and "World", concatenating them would result in "HelloWorld" or "Hello World", depending on whether you add a space in between. Concatenation can also apply to lists, arrays, or other data structures, where elements from multiple collections are combined into a single collection.
