You seem to have made up your mind about the advantages of TypeScript. The word "evangelism" has come up several times.

I'm a fairly junior dev, but I'd like to suggest caution to anyone who might be inclined to think that a technology like TypeScript will represent a clear step forward for anyone looking to take a step into 2022 and leave Javascript behind. The "evangelist". "Organizations/decision makers who haven't adopted TypeScript yet just haven't been exposed enough/had enough misconceptions debunked, and they need to get on the same page with faster moving companies, or get left behind".

1) I don't think this is how most successful companies/orgs think. 2) It seems to me that, as is the case with literally almost every choice of technology or solution, it's a matter of tradeoffs. Pros and cons. What are the honest disadvantages of your company adopting TypeScript? What are the opportunity costs, or how much quicker could you have addressed urgent sprints if you had left the JS alone? Be honest. Will there be a learning curve? I have to imagine there would at least be some friction... I don't think writing good TypeScript is as simple as doing a 1 hour tutorial plus some fiddling, or taking out a week. The other thing to weigh against that is, companies literally never have time. There is never enough time to do everything that you want to do, especially when it comes to stuff that's probably seen as more quality of life centric. Business oriented people want and are under pressure to put out features, tangible stuff.

The sooner you come to grips with that kind of stuff, will probably be the sooner you can do a solid job of framing and selling TypeScript. Be honest about the drawbacks, and then you can give them their due, while making sure that in your pitch, the payoffs are impossible to ignore. My final piece of advice might be to be a bit more gentle in your pitch. I've definitely run into some friction with what felt to me at that time like stubborn and short-sighted decision makers. Maybe the best thing you can do is to, again, frame the pros and cons, give them a fair and even-handed lay of the land, facts only, and then let it feel like it's them that's coming to the decision to use TypeScript. Almost like Jedi mind tricks.
