countLines.js

(function countLines() {
  let addedArr = [];
  let removedArr = [];
  document.querySelectorAll('#commit-files-summary .lines-added').forEach((n) => { addedArr.push(n.innerText) });
  document.querySelectorAll('#commit-files-summary .lines-removed').forEach((n) => { removedArr.push(n.innerText) });
  let added = addedArr
    .map((n) => parseInt(n))
    .reduce((a, b) => { return b + a } );
  let removed = removedArr
    .map((n) => parseInt(n))
    .reduce((a, b) => { return b + a } );
  return added + removed;
}())
