You won't be alone. In any real organization, you'll be part of an experienced team that's working towards the same goal as you, and if you're curious, open and appropriately humble, they'll teach you everything you need to know.
In fake organisations you'll be alone, surrounded by passive-aggressive office culture and every personality on the spectrum from always-hostile to Vulcan-autistic. If you're able, shop around for a job until you find one of these real organisations. They do exist.
Typewriters let you backspace _over_ what was already there, so we just typed the word, used backspace to get the beginning of the word, and then typed underscores until the word was effectively underlined.
In fact, you could double underline a word by moving half a line down (that was a thing) and then create the underline with equal signs.
It depends. In our current app, all we needed to implement separately was the margin for the status bar, literally two lines of code.
But as we move further, we'll be looking into making the versions for both platform feel truly native, and that will require some changes to navigation components and the overall navigation paradigm (tabs vs. drawer, screens vs. cards etc.).
The platform differences are as much about design as about code, and I don't see how you can escape that work with any cross-platform framework. But React Native makes it very easy to implement in a way that lets us share all but a few components.
The EU hasn't "announced" anything. There was a meeting between several influential people connected to the EU, and they reached an informal agreement on something related to freely accessible research. The "announcement" is nothing but the minutes of that meeting.
I thought I hated PDFs until I got my first Macbook and discovered Preview and two-finger zoom. Turns out, I just hated Acrobat and zooming with buttons.
