til - Today I Learned

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.

Topics I've Learned

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
6/7/2023	"SQL query"	SQL	aggregates are not allowed in the GROUP BY clause
6/15/2023	"SQL query"	SQL	can use EXTRACT('week' FROM date_column) or DATE_PART('week', date_column) to get the week number from a date
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
