What is the best way to exit an if statement once the desired condition is satisfied?

In my code, I am checking a specific variable for conditions and modifying that variable within the code. How can I prevent the if condition from checking again once the condition is met? If the else-if condition is triggered and date2 becomes null, the code goes back and checks if date2 still equals null, causing both conditions to be executed.

if(date) {
   if(date2 === null) {
        // block of code
       date2 = date;
    } 
    else if(date2) {
        // block of code
       date2 = null;
   }
}

Answer №1

let isCheckNeeded = true;
if(date){
   if(isCheckNeeded && date2 === null) {
        //execute this code block
        isCheckNeeded = false;
        date2 = date;
    }
    else if(date2){
        //execute this code block instead
        date2 = null;
    }
}
