JavaScript 'continue' within if statement

Within a for loop I can use break or continue. For example:

for(var i=0;i<5;i++){
  if(i=3){
    continue;   //I know this is absurd to use continue here but it's only for example
  }
}

But, what if I want to use continue from within a function within a for loop.

For example:

for(var i=0;i<5;i++){
  theFunction(i);
} 

function theFunction(var x){
  if(x==3){
    continue;
  }
}

I know that this will throw an error. But, is there any way to make it work or do something similar?

My solution would be, if putting for loop inside the function is not a big deal

function theFunction(initial, limit, jump) {
    for (var i = initial; i < limit ; i++) {
        if (i == jump) {
            continue;
        } else {
            console.log(i)
        }
    }
}

Use return value of that function and call continue based on it:

for (var i = 0; i < 5; i++) {
    if (theFunction(i)) {
        continue;
    }
}

function theFunction(x){
    if (x == 3) {
        return true;
    }

    return false;
}

Btw in your code you have if(i=3){, be aware that you need to use == or ===, single equals sign is for assignment.
