Final Practice Exercise Review
nesting if ... else
It is perfectly OK to put one if...else statement inside another one — to nest them. For example, we could update our weather forecast application to show a further set of choices depending on what the temperature is:
if (choice === 'sunny') {
if (temperature < 86) {
para.textContent = 'It is ' + temperature + ' degrees outside — nice and sunny. Let\'s go out to the beach, or the park, and get an ice cream.';
} else if (temperature >= 86) {
para.textContent = 'It is ' + temperature + ' degrees outside — REALLY HOT! If you want to go outside, make sure to put some sunscreen on.';
}
}Even though the code all works together, each if...else statement works completely independently of the other one.
