What type of clarification? Here false mean 0. So 0 + 7 = 7

True means 1. These are boolean values. Boolean can be either true or false.

True could refer to "something happened 1 time", while false could refer to "something happened 0 times" Examples: 5 == 9 ---> "5 equals 9" ---> false ---> "5 equals 9 happened 0 times" 3 > 2 ---> "3 is greater than 2" ---> true "3 is greater than 2 happened 1 time"

console.log(true + 7);// 8 In JS, true = 1; false = 0; That's why you got 7
