If you change it it definitely wouldn’t work. This highlighted statement is very important because it is basically includes a pre-written script into your JS. which will enable you to make use of the pre-written functions.

is it a directory :heart:


Is a js library that has all the function definitions like digitalWrite and so on.

You can directly call the function in your code and the code from library will do the work for you.
