Benchmark: bunch of ifs vs switch

Tests:

1
function getSupportedFormat(adaptiveLibrary){ var supportedFormat = ['mp4']; if (adaptiveLibrary == 'shaka') supportedFormat = ['dash', 'mp4']; else if (adaptiveLibrary == 'bitmovin') supportedFormat = ['hls', 'dash', 'mp4']; else if (adaptiveLibrary == 'hls') supportedFormat = ['hls', 'mp4']; return supportedFormat; } getSupportedFormat('hls')
2
function getSupportedFormat(adaptiveLibrary){ var supportedFormatsMap = { shaka:['dash', 'mp4'], bitmovin:['hls', 'dash', 'mp4'], hls:['hls', 'mp4'] }; return supportedFormatsMap[adaptiveLibrary] || ['mp4']; } getSupportedFormat('hls')
3
function getSupportedFormat(adaptiveLibrary){ switch(adaptiveLibrary){ case 'shaka': return ['dash', 'mp4']; break; case 'bitmovin': return ['hls', 'dash', 'mp4']; break; case 'hls': return ['hls', 'mp4']; break; default: return ['mp4']; } } getSupportedFormat('hls')
