Benchmark: Math.max/min vs if vs ternary vs bitwise & ~~ - 4 numbers

Script Preparation code:

var x = Math.random() * 1000;
var clientX = Math.random() * 1000;
var px = Math.random() * 1000;
var maxWidth = Math.random() * 1000;
function MAX_INT(a, b) {
  return a - ((a - b) & ((a - b) >> 31));
}

function MIN_INT(a, b) {
  return a - ((a - b) & ((b - a) >> 31));
}
function MAX(a, b) {
  const intA = ~~a;
  const intB = ~~b;
  return intA - ((intA - intB) & ((intA - intB) >> 31));
}

function MIN(a, b) {
  const intA = ~~a;
  const intB = ~~b;
  return intA - ((intA - intB) & ((intB - intA) >> 31));
}

Tests:

Math.max/min
Math.min(Math.max(x + clientX - px, 0), maxWidth) - x
if
if(x + clientX - px < 0) return 0; if(x + clientX - px > 750) return maxWidth; return x + clientX - px;
ternary
return x + clientX - px < 0 ? 0 : (x + clientX - px > maxWidth ? maxWidth : x + clientX - px) - x;
bitwise
MIN_INT(MAX_INT(x + clientX - px, 0), maxWidth)
& ~~
MIN(MAX(x + clientX - px, 0), maxWidth)
