Benchmark: if-else vs switch vs if

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 == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 3) { console.log("a is 4"); } else if (a == 2) { console.log("a is 2"); } else if (a == 1) { console.log("a is 1"); }
IF
const a = 1; if (a == 5) { console.log("a is 5"); } if (a == 4) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 3) { console.log("a is 4"); } if (a == 2) { console.log("a is 2"); } if (a == 1) { console.log("a is 1"); }
