Is it over-engineered? @glnnrys
@glnnrys
@glnnrys
Look into the source code 🤓 @glnnrys
The node_modules folder is your friend @glnnrys

Should I pick the most popular library? @glnnrys
@glnnrys
How about just roll my own? @glnnrys
¯\_(ツ)_/¯ @glnnrys
Rolling your own code allows you to Tailor code to
your exact needs @glnnrys
Rolling your own code gives you full control @glnnrys
With full control it's your responsibility to maintain and keep

Everytime we add more code into our library we increase
the spectrum for new bugs @glnnrys
Take risks and keep moving forward @glnnrys
Always start simple @glnnrys
Keep good practices that worked in the past. @glnnrys
Don't let new things intimidate you @glnnrys
Write the best code possible @glnnrys
One day old code becomes legacy. And if they are
great, we'll enjoy using older code even more. @glnnrys
“ ” Kent C. Dodds We should be mindful of
the fact that we don't really know what requirements will be placed upon our code in the future. @glnnrys
Keep using code what you know best @glnnrys
Never stop learning @glnnrys
