JavaScript Ternary Operator

Key Points:

• The ternary operator provides a concise way to write conditional statements in JavaScript.
• It is often used as a shorthand for simple if-else statements.
• The syntax consists of three parts: a condition, an expression if the condition is true, and an expression if the condition is false.
• The result of the ternary operator is the value of the expression that gets executed based on the condition.
• It offers a compact and readable alternative for short conditional assignments.
• The parentheses around the entire ternary operation are optional but can enhance readability.

Syntax:

condition ? expression_if_true : expression_if_false;

Example:

let age = 20;
let status = (age >= 18) ? 'Adult' : 'Minor';

 

Summary

The ternary operator is a useful tool for simplifying and enhancing the readability of conditional assignments in JavaScript.
