Here is a collection of tidbits and items I've learned along my coding journey.
This repo is inspired by the @jbrandchaud/til repo and the Learning in Public idea/movement.
I'll be starting off with some things I already 'know'. But don't implement often in an effort to create a habit of updating this every day.
date | topic | language/framework | breakdown |
---|---|---|---|
4/1/2023 | "__dirname" | expressjs | gives the directory name of the current module |
6/1/2023 | "quicksight" | SQL | curly brackets {} denotes a variable being used within the sql query |

6/27/2023 | "trunc/date_trunc" | SQL | differences: trunc works for both dates and floats, date_trunc works for dates only but can truncate specific date parts (day/month/week/etc) |
7/26/2023 | "interval" | SQL | used to help calculate date and time values |
5/15/2024 | "SQL query" | SQL | the split_part function is able to break apart a string by it's delimiter and return a selected subsection of the array |
