let a =prompt("hey whats your age");

a= Number.parseInt(a);

if (a<0){alert("this is an invalid age")}

if (a<9){alert("you are a kid and dont even think of driving")}

if (a<18 && a>=9){alert("you can think of driving after 18")}

if (a>18){alert("you are eligible for driving")}

//here we are working with the ternary operator which satisfies the condition at the same line

console.log("you can",(a<18?"not drive":"drive"))
