Script Preparation code:

this.number = Math.random() * 1000;

function max(v1, v2) {
  if (v1 > v2) return v1;
  return v2;
}

function min(v1, v2) {
  if (v1 < v2) return v1;
  return v2;
}

Tests:

Math.max/min
return Math.max(250, Math.min(750, this.number));
if
var number = this.number; if(number < 250) return 250; if(number > 750) return 750; return number;
ternary
var number = this.number; return number < 250 ? 250 : (number > 750 ? 750 : number);
custom function
return max(250, min(750, this.number));
