or

else if (Number(age) > 18) {
alert("Powering On. Enjoy the ride!");
}
else if (Number(age) === 18) {
alert("Congratulations on your first year of driving. Enjoy the ride!");
}
which of the syntax is better? and why?...relating to the Boolean condition of the if/else...if statement
That is not a question of syntax, the code you provided is good in any cases. However, if you want an accurate result and a clean code, you should transform your prompted result into a number. Keep in mind that Javascript in a dynamic typed language, so if the number as a string is compared to a number, they both will be compared as string.
