 var message = prompt(""); if(message == "coffee"){ alert("He like to drink a coffee very much, he always drink a coffee in the moring and in the afternoon for some they he drink coffee more one cup. If he have to work over time he have to drink a coffee again. In a month he drank coffee a lot cup.") }else if(message == "tea"){ alert( "He like to drink a tea very much, he always drink a tea in the moring and in the afternoon for some they he drink juice more one cup. If he have to work over time he have to drink a tea again. In a month he drank tea a lot cup.") }else{ alert('choose tea or coffee') }
