What type of if function code should I use?-CodePudding

There are two types of if function codes:

if (condition1) {
  function1
}
if (condition2) {
  function2
}
function3

if (condition2) {
  function1
} else {
  if (condition3) {
    function2
  } else {
    function3
  }
}

I don't know what is the correct way to use the if function code, I hope everyone can tell me.

Feel free to leave a comment if you need more information.

What type of if function code should I use? I would appreciate any help. Thank you in advance!

CodePudding user response：

else only runs when the if is not true. What you need to use depends on what you want it to do.

In your first example, if both condition1 and condition2 are true then both function1 and function2 will run. function3 will run regardless of the conditions.

In your second example when condition2 and condition3 are true, only function1 will run because it will never go in the else block. So function3 will only run when both condition2 and condition3 are false, and function2 will only run when condition2 is false and condition3 is true.
