Quick Reference Functions #

Framework Detection One-Liner #

// Quick framework detection
const getPopularFramework = () => typeof React !== 'undefined' ? 'react' : 
                                  typeof Vue !== 'undefined' ? 'vue' : 
                                  typeof ng !== 'undefined' ? 'angular' : 'vanilla';

Popularity Checker #

// Simple popularity checker
const isPopularFramework = (framework) => {
  const popularFrameworks = ['react', 'vue', 'angular', 'svelte'];
  return popularFrameworks.includes(framework.toLowerCase());
};

Framework Metrics Summary #

// Get summary of framework metrics
const getFrameworkSummary = (framework) => {
  const metrics = {
    react: { popularity: 'highest', learning: 'medium', jobs: 'most' },
    vue: { popularity: 'high', learning: 'easy', jobs: 'growing' },
    angular: { popularity: 'medium', learning: 'hard', jobs: 'stable' },
    svelte: { popularity: 'growing', learning: 'easy', jobs: 'limited' }
  };
  
  return metrics[framework] || { popularity: 'unknown', learning: 'unknown', jobs: 'unknown' };
};
