"Everything is an expression"... since ES1?

Many languages support "expression-only" semantics, allowing to use any construct in an expression position.

NOTE: the difference between expressions and statements is that the former produce a value, while the later don't.

For example, Ruby's if-expression:

x = 10

const obj = { a: 1, c: 3, b: 2 }

// Map from object.
const myMap = new Map(Object.entries(obj))

// Map to Object. 
// NOTE: Keys will be cast to strings by `.toString`, so any "complex" key like for example `[1, 2]` will become `1,2`
