We are moving from "make it work" to "make it work reliably at scale."
The 2.6 million contributors aren't there by accident.
They are there because the tool tunes the engineering life.
Does this match what you're seeing in your workflow?

There is a cost.
Productivity dips 20-30% during the learning phase.
We have to be honest about that.
But the long-term math works: up to 40% savings in maintenance costs over time.

The enterprise data confirms the shift.
78% of enterprise teams now use it.
Slack, Airbnb, Microsoft.
They aren't chasing trends.
They are prioritizing MAINTAINABILITY over short-term speed.

Then there is the satisfaction data.
TypeScript sits at 73% satisfaction. JavaScript is at 61%.
The gap comes down to CONFIDENCE.
When you refactor, the editor shows you exactly what broke. No guessing.

Teams adopting TypeScript report a 40-60% reduction in production-level bugs.
That is the real ROI.
You don't get `undefined is not a function` breaking your checkout flow.
It catches the error before the code even runs.

Here is the mechanism nobody talks about.
Microsoft Research analyzed 400 bugs.
They found 15% could be detected just by adding types.
That sounds low until you realize what those 15% cost in a production environment.

The data is clear: 2.6 million monthly contributors.
It surpassed Python.
But this isn't just about popularity metrics.
It is a signal that something FUNDAMENTAL is changing in how we value code quality.
