Check the Browser compatibility table carefully before using this in production.

<button>Select strong words</button>

JavaScript

let button = document.querySelector('button');

button.addEventListener('click', function () {
  let selection = window.getSelection();
  let strongs = document.getElementsByTagName('strong');

  if (selection.rangeCount > 0) {
    selection.removeAllRanges();
  }

  for (let i = 0; i < strongs.length; i++) {
    let range = document.createRange();
    range.selectNode(strongs[i]);
    selection.addRange(range);
  }
});
