Benchmark: switch case vs jump table vs bounce pattern vs ternary

Tests:

switch case
function thing(e) { switch (e) { case 0: return "0"; case 1: return "1"; case 2: return "2"; case 3: return "3"; } } for (let e = 0; 1e5 > e; e++) for (let e = 0; "3" != thing(e); e++) ;
jump table
function one() { return "0"; } function two() { return "1"; } function three() { return "2"; } function four() { return "3"; } let jumpTable = [ one, two, three, four ]; for (let a = 0; 1e5 > a; a++) for (let a = 0; "3" != jumpTable[a](); a++) ;
bounce patttern
function bounce(x) { if (x === 0) { return "0"; } if (x === 1) { return "1"; } if (x === 2) { return "2"; } if (x === 3) { return "3"; } } for (let e = 0; 1e5 > e; e++) for (let e = 0; "3" != bounce(e); e++) ;
ternary
function bounce(x) { return 0 === x ? "0" : 1 === x ? "1" : 2 === x ? "2" : 3 === x ? "3" : ""; } for (let e = 0; 1e5 > e; e++) for (let e = 0; "3" != bounce(e); e++) ;
