## The JavaScript toolchain rewrite
The older tools that helped cement JavaScript's place in stacks became uncool and suspicious.
## JavaScript's unexpected rise
JavaScript escaped its browser birthplace to run on phones, gaming consoles, microcontrollers and fridges.
## The language's resilience
Despite attempts to replace it, JavaScript kept evolving through ECMAScript releases and TC39 proposals.
## TypeScript's promise
TypeScript succeeded by accepting JavaScript wasn't going anywhere.
## The superpower we're giving away
JavaScript accelerated full-stack engineering by making the same language work across browsers and servers.
## Rust takes over toolchains
Rust, Go and Zig are rewriting JavaScript toolchains to be ten times faster.
## The speed trade-off
Rewriting toolchains in Rust shrinks the pool of JavaScript developers who can maintain them.
## Shiny object syndrome
Success breeds imitation as faster tools become the new standard for JavaScript tooling.
## The steam train paradox
We're laying faster tracks for a steam train that likes to take its time.
## Destination unknown
Faster tracks may not help JavaScript if the language itself can't keep up with the speed.
## The ultimate question
How far can we go before rebuilding the web from the ground up starts looking like the saner option?
## Key takeaway

JavaScript developers are optimizing toolchains with faster languages but risk losing the language's relevance as the ecosystem grows more complex.
