Is it possible to execute code if any of the "if...else if" statements were triggered?

I need to execute code if any of a series of conditional statements, such as if + else if + else if..., are true:

if(){
    ...
}else if(){
    ...
}else if(){
    ...
}
//run something if ANY of the above conditions are met

I don't want to clutter my code with the same line that needs to be executed after each if or else if.

My solution involves:

temp=i;//store a copy
i=-1;//make the change

if(){
    ...
}else if(){
    ...
}else if(){
    ...
}else{
    i=temp//restore original value if none was executed
}

This setup guarantees the change will take place regardless and restores the initial state with an else. However, I am concerned about the readability of this approach.

Are there clearer and more readable alternatives for achieving the same outcome?

Answer №1

Here's a solution for you

let checkCondition = true;
if (...) {
} else if (...) {
} else if (...) {
} else {
  checkCondition = false;
  // or: return, if it's inside a function!
}
if (checkCondition) {
  // one of the conditions was met.
}

If you encapsulate this code in functions, you can simply use return in the final else block for a cleaner implementation.

Answer №2

Is there a specific reason for having two variables in this scenario? Here's an alternative approach:

let isConditionMet = true;

if(){
    ...
}else if(){
    ...
}else if(){
    ...
}else{
    isConditionMet = false;
}

if(isConditionMet){
    ...
}

In terms of enhancing readability, it would be beneficial to choose a descriptive name for the variable that accurately reflects its purpose.
