The two expressions are separated by a colon.ifFalseExpression is executed if the condition evaluates to false.ifTrueExpression is executed if the condition evaluates to true.
The condition is followed by a question mark, ?. condition is the Boolean expression you want to evaluate and determine whether it is true or false.
The general syntax for the ternary operator looks something similar to the following: condition ? ifTrueExperssion : ifFalseExpression The operator is called "ternary" because it is composed of three parts: one condition and two expressions. How to Use the Ternary Operator in JavaScript – a Syntax Overview
It always returns a value: The ternary operator always has to return something. It enhances performance: In some cases, the ternary operator can perform better than an if.else statement because the ternary operator gets evaluated in a single step. It provides flexibility: The ternary operator has many use cases, some of which include: assigning a value to a variable, rendering dynamic content on a web page, handling function arguments, validating data and handling errors, and creating complex expressions. The ternary operator will reduce the amount of nesting that occurs when using if.else statements. This comes in handy when writing multiple conditional statements. Your code will be more organized: The ternary operator will make your code more organized and easier to maintain. Your code will be more readable: When writing simple conditions, the ternary operator makes your code easier to understand in comparison to an if.else statement. You will write short conditional statements and fewer lines of code, which makes your code easier to read and understand. Your code will be more concise: The ternary operator has minimal syntax. You may want to use the ternary operator for a few reasons: Why Use the Ternary Operator in JavaScript? The ternary operator ( ?:), also known as the conditional operator, is a shorthand way of writing conditional statements in JavaScript – you can use a ternary operator instead of an if.else statement.Ī ternary operator evaluates a given condition, also known as a Boolean expression, and returns a result that depends on whether that condition evaluates to true or false.
