Returns Boolean depending if passed AST contain only empty space

§ Quick Take

import { strict as assert } from "assert";
import containsOnlyEmptySpace from "ast-contains-only-empty-space";

    a: [
        x: {
          y: [
              z: ["\n"],
    b: ["\t\t\t  "],
    c: ["\n \n\n"],
    d: ["\t   "],

§ Examples

§ Purpose

Working with parsed HTML is always a battle against the white space. This program tells if given data structure is empty — containing only empty space or really empty.

By the way, weird things which don't belong to parsed structures (functions, for example) will yield a result false.



Input - anything. Output - Boolean.

This library does not mutate the input arguments.
