Condition

In this section, all the methodologies are just for best practice. That's for most easy to read and maintain.

Straight forward logic

• Take care the true condition first

    if (flag) {
  
    } else {
  
    }

  not

    if (!flag) {
  
    } else {
  
    }

  Also, remember to have curly brace, don't omit them even only line of statement.

• Use straight forward logic

    if x is not None:

  not

    if not x is None:

  All the code fragments are logic correctly, but please approach best practice.

• Ternary operator

  Use it when it's short and simple; otherwise, use if else.

    var a = flag ? b : "";

Multiple condition

• Multiple or/not

  • For easy to read, bread down multiple lines

      if (
          myObjects.length > 0 &&
          flag == true
      ) {
    
      }

  • Unless, they are very short

      if (a > 0 && b > 0) {
    
      }

• Multiple functions

    if (
        isNew(myObjects) &&
        containsNumber(myObjects)
    ) {
  
    }

  In the example, if isNew() is false, then containsNumber() won't be executed.

  You don't do the following code; unless isNumber is going to use again.

    var isNewObjs = isNew(myObjects);
    var isNumber = containsNumber(myObjects);
    if (isNewObjs && isNumber) {
  
    }
