Built-in functions are like the secret helpers of programming.
They come already included in programming languages and offer many tools we can use right away.
For example, we can easily do math, change words, or manage data. Because these functions are ready to go, programmers can spend less time creating and fixing their code. This lets them focus on solving problems instead of starting from scratch.
On the other hand, user-defined functions let programmers create their own special functions for their unique needs. Making these functions
