Microsoft Program Manager Mistakenly Tweets Office 365 Will Be Rewritten in JavaScript (thurrott.com)

"A Microsoft employee claimed publicly that 'all of Office 365' was being 'completely rewritten' in JavaScript," writes Paul Thurrott, adding "And then all hell broke loose." First things first. It's not true. So if you were freaking out that Microsoft was somehow abandoning C# and C++ for its most mission-critical offerings, freak out no more. It's not happening. So what is happening? A Microsoft program manager named Sean Larkin perhaps got a little overly-exuberant on Monday... he tried to clarify things in follow-up tweets when his original missive exploded intro controversy. Which shouldn't have been a surprise. And yet, somehow, it was...

[H]e finally corrected himself on Reddit, blaming Twitter's character limitations for his many factual errors. "We are not abandoning C++, C#, or any of the other awesome languages, APIs, and toolings that we use across Microsoft," he clarifies. "Nothing [in Office 365] is converting to 'all/completely' JavaScript/TypeScript."
Thurrott, a long-time Windows blogger, concludes that "getting something this big this wrong is inexcusable."

And yet, Windows soldiers on.

I don't care what language you use.

I care whether your programs suck. You can write good stuff in JavaScript. You can also deliver lazy-ass applications in JavaScript. That isn't determined by your language, it's determined by your management and commitment to quality.

[This isn't specific to Microsoft in any way.]

Not a mistake

From what I can collect, the UI for O365 and other browser based tools in the future will be rewritten with a React/Electron/JS focus.

They're already in JS and HTML obviously or they wouldn't work in the browser. But right now those things are a mess.

I'm sure, and I don't know who assumed, that the server-side would be completely rewritten with a UI-oriented framework.
