Conditional Statements in JavaScript

Conditional Statements in JavaScript Making Decisions in Code In JavaScript, conditional statements are used to make decisions in a program. They help the program choose what action to perform based on whether a condition is true or false . Conditional statements make your code smart and interactive . For example: If the user is 18 or older → allow voting Else → show not eligible message JavaScript mainly provides these conditional statements: if if...else if...else if...else switch Let’s understand each one with examples. 1) if Statement The if statement is used when you want to execute a block of code only if a condition is true . Syntax if ( condition ) { // code to execute } Example let age = 20 ; if ( age >= 18 ) { console . log ( " Eligible to vote " ); } Output Eligible to vote Here, since age >= 18 is true, the message gets printed. 2) else Statement The else block runs when the condition inside if is false. Syntax if ( condition ) { // true block } else { // false block } Exam
