Interview Questions with Answers: 1. What are conditional statements in JavaScript? Conditional statements allow the program to make decisions based on conditions. They control the flow of execution depending on whether a condition is true or false. 2. What is the difference between if and switch? The if statement checks multiple types of conditions, while switch is mainly used when comparing one value with many possible cases. 3. What is an else if ladder? An else if ladder allows checking multiple conditions sequentially. When one condition becomes true, the remaining conditions are skipped. 4. When should we use switch instead of if else? Switch is useful when checking the same variable against many values. It makes the code cleaner and easier to read. 5. Can we use nested if statements in JavaScript? Yes, JavaScript allows nested if statements, meaning an if statement inside another if statement for more complex conditions.
