I feel like JS needs auto-currying.

    function greet(greeting, name) {
       return `${greeting} ${name}`
    }

    const greetWithGreetingHello = greet('hello')
    greetWithGreetingHello('sally')

And this should work with named arguments too.

    function greet({greeting, name}) {
        ...
    }

    const greetWithGreetingHello = greet({greeting: 'hello'})
    greetWithGreetingHello({name: 'sally'})

With named params, curried functions can be read more naturally too.

greetWithGreetingHelloAndWith({name: 'sally'}).

"and with name sally"

I'm responding to an unrelated old comment of yours about questioning all assumptions. In Forth, Chuck Moore said local vars are dangerous. Rather, everything should be a global. (However multithreaded Forth implementations do require locals.)

the key idea for me was realizing that variables are really 3 things: value, type, and identifier.

A javascript object is like an S-expression if you squint. The subtree nesting is messier.
