Summary

Fix performance inefficiencies: repeated object/array allocation in hot paths and sequential API calls that can run in parallel.

app.js

  • Move nickColors array out of nickColorClass() — was recreated on every call
  • Move htmlEscapeMap out of escapeHtml() — was recreated on every regex match

cla-mark.yml

  • Parallelize ensureLabel() calls with Promise.all() — labels are independent
// Before: object created per character match
function escapeHtml(s) {
  return s.replace(/[&<>"']/g, (c) => ({ '&': '&amp;', ... }[c]));
}

// After: single allocation
const htmlEscapeMap = { '&': '&amp;', '<': '&lt;', '>': '&gt;', '"': '&quot;', "'": '&#39;' };
function escapeHtml(s) {
  return s.replace(/[&<>"']/g, (c) => htmlEscapeMap[c]);
}

@copilot could you help us solve "// Before: object created per character match
function escapeHtml(s) {
return s.replace(/[&<>"']/g, (c) => ({ '&': '&', ... }[c]));
}

// After: single allocation
const htmlEscapeMap = { '&': '&', '<': '<', '>': '>', '"': '"', "'": ''' };
function escapeHtml(s) {
return s.replace(/[&<>"']/g, (c) => htmlEscapeMap[c]);
}" this please? =)
