d3-selection/src/selectAll.js

Data-driven DOM manipulation: select elements and join them to data.

import array from "./array.js";
import {Selection, root} from "./selection/index.js";

export default function(selector) {
  return typeof selector === "string"
      ? new Selection([document.querySelectorAll(selector)], [document.documentElement])
      : new Selection([selector == null ? [] : array(selector)], root);
}
