confused about var itemToBuy

I do not understand why the correct answer to "After this code runs, what is the value of the variable itemToBuy?" is actually the correct answer.

var itemToBuy = ''; var savings = 1000; if ( savings > 500 ) { itemToBuy = 'Computer'; } else if ( savings > 200 ) { itemToBuy = 'Phone'; } else if ( savings > 0 ) { itemToBuy = 'Dinner'; } else { itemToBuy = '...still saving...'; }

you just need to check which condition its true. 

var itemToBuy = '';
var savings = 1000;

if (savings > 500) { 
    itemToBuy = 'Computer';
//here is saying if savings is more than 500. then item to buy is computer if its less is going to check the next condition.
// in the savings variable you have 1000 which is more then 500. that means the first condition will run because its true
// if its false then  it will check the next else if.

} else if (savings > 200) {
    itemToBuy = 'Phone';
}
else if (savings > 0) {
    itemToBuy = 'Dinner';
}
else {
    itemToBuy = '...still saving...';
}

i hope this makes sense
