Why in the following code the first condition passed so only it's code ran? Can you please explain

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...'; }

In the if statement the conditions are tested from top to bottom until it finds a condition that matches. In this case the first condition matched: savings is equal to 1000, so 1000 is greater than 500 so its true. Once a condition is met in an if staement it drops out of the loop and continues onto the rest of the code. Only one condition in an if statement can work (if there is one that matches).
