And remember, if something you learnt was a big win for you, then you know where to drop it as well.👇👇🏻👇🏼👇🏽👇🏾👇🏿

I started working with mapbox for a feature at work. I've learned a bit about sources, layers, and mapbox studio. I need to figure out how to turn geojson data in to shapes. I found the mapbox Tippecanoe tool, but haven't managed to generate something useful yet.

In my free time I learned a bit about v-slots and the vue router.

I'm working my way through a JS course and learnt about optional chaining and nullish coalescing operator (seriously what kind of name is that...)

The nullish coalescing operator comes from C# as far as I know, much like async/await came from .NET. In terms of the name it’s a little long, but it makes sense. Naming is hard. 😎
