For me its still secret why many companies want their employees work in the offices. Especially in the IT. Because, all that you need for your work is a laptop and the internet connection.

in this code ```if( ! condition ){ if( ! another_condition ){ //do something } } the second if ( ! another_condition ) will be called only in the 1 st condition was true . In this code ` `` if (condition){ //return } if (another_condition){ //return } //do something you will call 1st if and the 2nd regardless of the 1st one. Just choose the case you need.
