That is, javascript "short circuits" the evaluation of boolean operators and will return the value associated with either the first non false variable value or whatever the last variable contains. see anurag's explanation of those values that will evaluate to false. using this technique is not good practice for several reasons; however. 4 in javascript you have also the ===. = this is for set the value to the variable. == this is for compare if the value is the same. === this is for compare if the value is the same and also the type is the same.
