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)
