Script Preparation code:

var rnd = Math.random;
var branchlessMin = (a, b) => (a > b) * b + (a <= b) * a;
var mathMin = Math.min;
var minTernary = (a, b) => a > b ? b : a;
var minIf = (a, b) => {
   if (a > b) {
     return b;
   } else {
     return a;
   };
};

Tests:

branchless
return branchlessMin(rnd(), rnd());
Math.min (cached)
return mathMin(rnd(), rnd());
Math.min (uncached)
return Math.min(rnd(), rnd());
Min w/ Ternary
return minTernary(rnd(), rnd())
Min w/ If
return minIf(rnd(), rnd())
