[removed] use either a variable, or if it's undefined, a default string

Question

I have this code:

var phrase = function (variable, defaultPhrase) {
    if (typeof variable === \"undefined\") {
        return defaultPhrase;
    }
    else         


        

Answer 1

Shouldn't it be:

var phrase = function (variable, defaultPhrase){
    if(variable == undefined){
        return defaultPhrase;
    }else{
        return variable;
    }
}
