Dead code elimination

Dead code elimination is like cleaning up your room. Imagine you have lots of toys in your room, but you don't play with all of them anymore. You only play with some of your favorite toys. So, it would be a good idea to remove the toys you don't play with anymore to make more space for your favorite toys, right?

Dead code elimination is similar to that. In a computer program, there might be some code that is not used anymore, just like the toys you don't play with anymore. This code takes up space and memory, even though it's not doing anything useful. So, just like you clean up your room and remove the toys you don't play with, a computer program can remove the code that is not used anymore to free up space and improve performance.

This process is called dead code elimination. It helps computer programs run faster and more efficiently by getting rid of the unnecessary code and making the useful code work better. Just like cleaning up your room can make it easier to find your favorite toys and play with them, dead code elimination makes it easier for the computer program to focus on the important things and work better.
