Total beginner bere, could somebody explain why this if statement isnt working?
var name = prompt("Please tell me your name?"); if (name != null) { alert("Hello " + name + "! How are you?"); } else { alert("You didn\'t enter a name!"); } How would I check if the prompt string is 'null/empty'? Thanks!
