Benchmark: if-else vs switch case

Tests:

Switch case
const a = 1; switch (a) { case 5: console.log("a is 5"); break; case 4: console.log("a is 4"); break; case 3: console.log("a is 4"); break; case 41: console.log("a is 4"); break; case 31: console.log("a is 4"); break; case 42: console.log("a is 4"); break; case 33: console.log("a is 4"); break; case 44: console.log("a is 4"); break; case 35: console.log("a is 4"); break; case 46: console.log("a is 4"); break; case 37: console.log("a is 4"); break; case 48: console.log("a is 4"); break; case 39: console.log("a is 4"); break; case 40: console.log("a is 4"); break; case 311: console.log("a is 4"); break; case 422: console.log("a is 4"); break; case 333: console.log("a is 4"); break; case 444: console.log("a is 4"); break; case 355: console.log("a is 4"); break; case 2: console.log("a is 2"); break; case 1: console.log("a is 1"); break; }
if-else
const a = 1; if (a === 5) { console.log("a is 5"); } else if (a === 4) { console.log("a is 4"); } else if (a === 3) { console.log("a is 4"); } else if (a === 41) { console.log("a is 4"); } else if (a === 31) { console.log("a is 4"); } else if (a === 42) { console.log("a is 4"); } else if (a === 33) { console.log("a is 4"); } else if (a === 44) { console.log("a is 4"); } else if (a === 35) { console.log("a is 4"); } else if (a === 46) { console.log("a is 4"); } else if (a === 37) { console.log("a is 4"); } else if (a === 48) { console.log("a is 4"); } else if (a === 39) { console.log("a is 4"); } else if (a === 40) { console.log("a is 40"); } else if (a === 311) { console.log("a is 311"); } else if (a === 422) { console.log("a is 422"); } else if (a === 333) { console.log("a is 333"); } else if (a === 444) { console.log("a is 444"); } else if (a === 355) { console.log("a is 355"); } else if (a === 2) { console.log("a is 2"); } else if (a === 1) { console.log("a is 1"); }
