Video Name: Core Modules

- core modules are the modules already built into node.js
- there are a lot of them
- fs = file system module
- you don't use the /. in core modules, only custom modules, use only the name (node knows its a core module)
- allows you to read and write files, and delete them
- file system module has 3 parameters
- path module, works with paths, normalizes slashes,
- "setInterval" - can have a bit of code to run, runs repeatedly, similar to the process of "setTimeout" but repeats unlike "setTimeout"
- "dirname" - give directory name (full path)
- "filename" -give file name of whatever file is currently calling the code
