Multiple conditions in an if clause

Question

If I have an if statement that needs to meet these requirements:

if(cave > 0 && training > 0 && mobility > 0 && sleep > 0)
         


        

Answer 1

Sounds like a job for a "validator" function like this:

function areAllGreaterThanZero(){
    //TODO: check inputs
    var result = true;
    [].splice.apply(arguments).forEach(function(x){ 
        result = result && (x > 0); 
    });
    return result;
}

if(areAllGreaterThanZero(cave, training, mobility, sleep)) {
    // ...
}
