Front-End-Developer - Level 1 In other words, when I earlier said "If the condition in the parentheses is true, then the first statement is run," it's more precise to say "If the condition in the parentheses evaluates to true , then the first statement is run." (Note: this isn't 100% correct, as we'll see in the next lesson, but don't worry about that for now.) Summary One branch: if (age > 21) { } $('#drinks').show(); Two branches: if (age > 21) { $('#drinks').show(); } else { $('#under-21').show(); } Three branches: if (age > 21) { $('#drinks').show(); } else if (age === 21) { $('#drinks').show(); } else { $('#under-21').show(); } Branching can use a variable whose value is a boolean: var over21 = true; if (over21) { $('#drinks').show(); } Comparison operators: === , > , < , >= ,
Front-End-Developer - Level 1 3 > 2; // returns true = sets a variable; === compares two things. Don't use == . Branching 123
