Sell Me On Typescript

I’m a Python developer and this strictly typed langauges this something I left after I finished my Diploma (C, C++, Java)

I later got into React and all those web dev stuffs that the kids are into. At that time javascript was all you really needed. Then the wave of Typescript hit and everyone jumped on.

I get all the “advantages” of it, but in the past few months I looked into it and decided to rebuild my portfolio with it - the portfolio is still not done.

Most of my time was spent making Typescript happy and not building.

So, you Typescript pundits, why must I use it?
