JavaScript Conditional Statements Explained: if, else, and switch

JavaScript conditional statements allow programs to execute different blocks of code depending on whether a condition evaluates to true or false. Developers use these statements to handle real-world decision-making scenarios, such as checking login status, verifying payment success, or displaying product availability. The main types include the if statement, if...else, if...else if...else, nested if, and switch statements. Each type serves a specific purpose, from handling a single condition to managing multiple branching outcomes. Understanding these constructs is fundamental to building dynamic and interactive web applications in JavaScript.
