JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - If Else Statements in JavaScript and (in) Equalit

The video tutorial explains the concept of conditional logic in JavaScript, focusing on if-else statements and boolean data types. It covers how these statements execute code blocks based on true or false conditions, providing flexibility in programming. The tutorial includes a practical coding example to demonstrate the use of if-else statements and encourages experimentation with different conditions to understand their impact on code execution.

What is the primary difference between assignment operators and quality operators?

• Assignment operators compare values, while quality operators assign values.

• Both operators are used for comparing values.

• Assignment operators assign values, while quality operators compare values.

• Both operators are used for assigning values.

Which data type is used in JavaScript to represent true or false values?

• Number

• Boolean

• String

• Array

What is the purpose of an if-else statement in JavaScript?

• To execute code based on a true or false condition.

• To loop through a set of instructions.

• To declare variables.

• To define functions.

In the coding example, what will the function return if X is 2 and Y is 3?

• Null

• False

• True

• Undefined

What happens if the condition in an if statement is false?

• Nothing happens.

• The program crashes.

• The code block inside the else statement is executed.

• The code block inside the if statement is executed.

How can you modify the condition to check if X is less than or equal to Y?

• Use the operator '!='

• Use the operator '<='

• Use the operator '>='

• Use the operator '=='

What will be the output if X is changed to 4 in the example?

• Error

• Undefined

• False

• True
