Like many coders, I do not build everything from scratch—I rely on preexisting code, called software libraries, to create new systems. Think of it like a home improvement project. If I want to build a fence, I don’t need to personally chop down trees for my posts. I can go to the hardware store and buy prefabricated items, like precut planks of wood that fit my vision. Software libraries are lines of code written by other coders, like prefabricated building blocks, and they can be downloaded online by almost anyone.
