Best performance if-statements

Question

Im wondering what the best way to make an if statement is.

Im working on a project that is looping 10,000 times, so readibility is not a priority. Just performance

if (5 > 6) {
var h = true;
}
^ has brackets {}

if (5 > 6)
var h = true;
^ no brackets

var h = 5 > 6 ? true : false;
^ ternary operator

Answer 1

{} Doesn't effect on your performance. Unnecessary looping and unnecessary condition effect on your performance.

That is just a way to write single line statement without using {} but if there are multiline statement then you cannot ignore to use {} because it denotes a block of code.

Ternary operator doesn't make sense here because 5 > 6 would return either true or false so just

h = 5 > 6;

one more example:

if (5 > 6)
return true;
else
return false;

this also doesn't make sense because you can directly do like this:

return 5 > 6; // this will take less time rather than above

Answer 2

That depends on the complexity and length of the conditional code and your personal preference.

To be sure, you can use the {} ersion

Answer 3

I would eliminate the if statement altogether and just assign the Boolean result.

var h = 5>6
