Hi there kiddo! Do you like playing with building blocks? Well, imagine you have a lot of different ones, but some of them are too complicated for you to understand. What would you do? That's where a wrapper library comes in!
A wrapper library is like a special set of instructions that helps you use those complicated building blocks without having to figure out all the complicated things they do. It's like a cool box that takes your complex building blocks and puts a simple one on top of it, so you can use it without any problems.
In computer terms, a wrapper library makes it easier for programmers like mommy or daddy to use a complicated code (the building blocks), by making a simpler code that covers it (the simple block). For example, if they want to use a code to connect to a database, they can use a wrapper library that makes it easier to connect to the database without having to worry too much about the complicated details.
So, just like a wrapper for a gift or a candy makes it look pretty, a wrapper library makes complicated codes easier to use. Pretty cool, huh?
