hoistage

hoist.js

// Difference between lintability/RTE of hoisting vs non-hoisted code

// ReferenceError: foo is not defined
//    at <anonymous>:3:5
try {
    foo()
    const x = 1;
    const foo = () => x;
} catch(e) {
    console.log(e)
}

// Hoisted version - you get a longer stack.
// Statically analysable (lintable): foo2 depends statically on const x, and foo2() is called before const x
// is in scope.

// ReferenceError: x is not defined
//    at foo2 (<anonymous>:14:23)
//    at <anonymous>:12:5
try {
    foo2()
    const x = 1;
    function foo2() { x };
} catch(e) {
    console.log(e)
}
