Is it wrong to declare a variable inside an if statement in Javascript?

Question

I have a Sublimelinter installed in Sublime Text 2 and it\'s great. However it doesn\'t like the following code:

if(condition){
    var result = 1;
}else{
           


        

Answer 1

I recommend doing this:

var result = MORE_LIKELY_OUTCOME;

if (LESS_LIKELY_CONDITION) {
    result = LESS_LIKELY_OUTCOME;
}

process(result);

This way, you are setting result initially to what you are expecting it to be most of the times. Then, the if statement will change result if the condition occurs.
