Which is best way to execute scope of code inside loop? Splitting it into functions. Calling nested functions as inner functions or calling function outside loop?

• test without functions took: 158.88999996241182 ms
• test with calling functions inside took: 170.85500003304332 ms
• test with calling functions outside took: 165.08999996585771 ms
• test with calling functions inside depending on global parm took: 310.6550000375137 ms

Let's assume I have to check three different cases. Is it better to use if/else or switch?

• switch took: 21.1999999883119 ms
• if/else took: 14.66499999514781 ms

I've worked on function that requires a heavy usage of if/else statement. I came up with an idea. Object with keys return the result.

const condition = {
  up: x1 > x2 && y1 > y2,
  down: x1 < x2 && y1 < y2
};
