I was wrote Typescript this week for the second time in my life. Learning new things is hard. Learning them without adequate documentation or a person to point you in the right direction is a test of perseverance.
It’s amazing to me that junior engineers can grow at all in this industry. Senior engineers that are too busy to document how things work and in too many meetings to talk to.
If you’re a senior engineer, documentation can be one of the biggest impacts you can have in your organization. Teaching junior engineers can help you learn faster than going off on your own to build new things.
