var result = Math.max(min, Math.min(max, value));
xxxxxxxxxx1
function keepRange(value, min, max) {2
return Math.max(min, Math.min(max, value));3
}4
5
6
// Usage example:7
8
// value min max9
console.log(keepRange( 2, 1, 5 )); // 210
console.log(keepRange( 0, 1, 5 )); // 111
console.log(keepRange( 6, 1, 5 )); // 512
console.log(keepRange( 1, 1, 5 )); // 113
console.log(keepRange( 5, 1, 5 )); // 514
console.log(keepRange( -2, 1, 5 )); // 1
