Modern Web Build Toolchain

I was looking at Postman, the API building, testing, maintaining repositories company hosting & developing the Postman products.

Then I saw in their Technician hires requirements this line –

Extensive experience with libraries in the modern web build toolchain such as Webpack, esbuild, Babel, Mocha, Jest, Enzyme

These are the “modern web build toolchain”?

Wow! It"s crazy out there. Every year the experience requirements grow for “tools” new hires should be up-to-speed in. Impossible to master all the new platforms for tools used for “web build”.
And now API s have become a whole Provider Enterprise in themselves!
