Solution 1:[1]

You can use if statement. If object is null then length is 0 otherwise get the length by using length property of that object.

Solution 2:[2]

Before using .length property, check whether the variable is null/undefined/or some other falsy value. If Yes then assign length 0 else calculate the length. Eg :

var reference,   // ref is undefined
    refLength; 

if(reference) {
    refLength = reference.length;
}
else {
    refLength = 0;
}
