Real type of

Retrieve the real type of a variable. A more accurate version of the typeof operator.

real_type_of("") === "string";
real_type_of() === "undefined";
real_type_of(42) === "number";
real_type_of({}) === "object";
real_type_of([]) === "array";
real_type_of(null) === "null";
real_type_of(new Date()) === "date";
real_type_of(new Set()) === "set";
real_type_of(new WeakSet()) === "weakset";
real_type_of(new WeakMap()) === "weakmap";
real_type_of(() => {}) === "function";
real_type_of(async () => {}) === "function";
real_type_of(function* () {}) === "function";

Pass in true as a second parameter to get even more accurate results

real_type_of(() => {}, true) === "function";
real_type_of(async () => {}, true) === "asyncfunction";
real_type_of(function* () {}, true) === "generatorfunction";
// ... everything else remains the same
