Benchmark: switch vs if else improved

Tests:

switch
const SOURCE = [ 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', 'hello', 'hi', 'bye', 'die', 'die', 'bye', 'hi', 'hello', ]; let a; for(let i = 0;i<100;i++){ for(let value of SOURCE){ switch (value) { case "ahello": a = (value + "\n\n" + "hi"); break; case "ahi": a = (value + "\n\n" + "hello"); break; case "abye": a = (value + "\n\n" + "no"); break; case "adie": a = (value + "\n\n" + "you shot me"); break; case "bhello": a = (value + "\n\n" + "hi"); break; case "bhi": a = (value + "\n\n" + "hello"); break; case "bbye": a = (value + "\n\n" + "no"); break; case "bdie": a = (value + "\n\n" + "you shot me"); break; case "hello": a = (value + "\n\n" + "hi"); break; case "hi": a = (value + "\n\n" + "hello"); break; case "bye": a =(value + "\n\n" + "no"); break; case "die": a = (value + "\n\n" + "you shot me"); break; default: break; } } } console.log(a)
