![]() ![]() Else print “Number is odd” if the number returns a remainder when divided by 2.The else if statement also takes a condition. You can add as many else if statements as you’d like, to make more complex conditionals The else if statement always comes after the if statement and before the else statement. The if.else. The else if statement allows for more than two possible outcomes. If the condition is false, the if.else statement executes the block that follows the else branch. Condicional que ser executada caso a condio em if seja verdadeira (true). Uma expresso (premissa) que pode ser avaliada como verdadeira (true) ou falsa (false), veja lgica de programao para entender melhor. ![]() If the condition is true, the if.else statement executes the block that follows the if branch. if (condio) afirmao1 else afirmao2 condio. Print “Number is even” if the number is divisible by 2. The if.else.if statement checks the conditions from top to bottom and executes the corresponding block if the condition is true. Code language: JavaScript (javascript) In this syntax, the condition is a value or an expression that evaluates to true or false.Check if a number is odd or even in JavaScriptįunction `isEvenOrOdd()` checks if input number is even or odd by using “%” operator in JavaScript. It's the only one JavaScript currently has, though.1. They can even be chained: serveDrink(userIsYoungerThan4 ? 'Milk' : userIsYoungerThan21 ? 'Grape Juice' : 'Wine') īe careful, though, or you will end up with convoluted code like this: var k = a ? (b ? (c ? d : e) : (d ? e : f)) : f ? (g ? h : i) : j ġ Often called "the ternary operator," but in fact it's just a ternary operator. ![]() Syntax The if statement starts with a if followed by condition in parentheses. Like all expressions, the conditional operator can also be used as a standalone statement with side-effects, though this is unusual outside of minification: userIsYoungerThan21 ? serveGrapeJuice() : serveWine() If Else Statement Multiple conditions using else if Nested if References If statement The JavaScript if statement executes a block of code if the evaluation of condition results in truthy. ![]() ServeDrink(userIsYoungerThan21 ? "Grape Juice" : "Wine") If the condition is falsy, another statement in the optional else clause will be executed. This can be shortened with the ?: like so: var userType = userIsYoungerThan18 ? "Minor" : "Adult" The if.else statement executes a statement if a specified condition is truthy. For example, if the condition2 is true, the if.else.if statement won’t evaluate the condition3. The if.else.if statement stops evaluating the remaining conditions as soon as a condition is true. Here is an example of code that could be shortened with the conditional operator: var userType The if.else.if statement checks the conditions from top to bottom and executes the corresponding block if the condition is true. The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark ( ), then an expression to execute if the condition is truthy followed by a colon ( : ), and finally the expression to execute if the condition is falsy. This is a one-line shorthand for an if-else statement. ![]()
