better-sqlite3

• great for prototyping all kinds of apps (non production usages) or unit testing
• pretty good experience with raw queries

sequelize

• it's an orm, so boooo!
• plug n play
• creation of models feels mandatory (sequelize-auto can be used to auto-generate your models if there's an existing db)
• there is no pluck() to flatten queries like select * from table1 (currently resolving this by writing out another variable for every query)

// Climbing Stairs (5/13)
//  - can be modeled as a graph problem
//  - starting from 0 we can take 1 step and get to 1 or take 2 steps and get to 2
//  - then from 1 we can take 1 step and get to 2 or take 2 steps and get to 3, and so on
//  - if we get to n from a branch, we've found one way
//  - recursion can be used to count number of unique paths that can count to n
//  - to avoid repeated work, we can cache
//  - if we don't cache, it's 2^n time because we must branch out two ways, n times
//  - if we cache, it's linear time/space
//  - finally, we can reduce to constant space by computing total distinct ways
