Knowing what to learn has always been an implicitly vital skill to career growth. Maybe it’s all right fewer people will know regex, just like as each year passes relatively fewer people know about var hoisting in JS

What does the business benefit from you handwriting regex vs a clanker?

The benefits of knowing regex is not about the syntax (that’s what docs/google/books are for), but knowing when it’s right to use it.

Immersion with the codebase is not about coding and syntax (which is actually very easy for me). It’s about being able to intuit that a particular combination can result in a buggy state and provides the wrong result downstream. You lose that you stay in the dreamland of specs.
