Understanding Conditional Statements in Code.org Unit 4 Lesson 7

What is the primary purpose of a conditional statement in programming?

• To repeat a block of code multiple times

• To stop the program

• To execute a block of code if a specific condition is true

• To declare variables

Which of the following is a correct syntax for an `if` statement in JavaScript, which is used in Code.org's programming environment?

• `if condition { }`

• `if (condition) { }`

• `if [condition] { }`

• `if { }`

What will the following code snippet display if the variable `score` is 90? ```javascript if (score > 85) { console.log("Excellent"); } else { console.log("Good"); } ```

• Good

• Excellent

• Nothing

• Error

In an `if-else` statement, how many times is the code block executed if the condition is true?

• 0

• 1

• 2

• As many times as the condition remains true

Which of the following conditions will return `true` if `x` is equal to 10?

• `x > 10`

• `x < 10`

• `x == 10`

• `x != 10`

What is the role of the `else` statement in a conditional structure?

• It specifies a new condition to test, if the first condition is false.

• It stops the execution of the program.

• It executes a block of code if the condition in the `if` statement is false.

• It repeats the execution of a block of code.

How can you execute multiple conditions sequentially in JavaScript?

• Using multiple `if` statements

• Using `if` followed by multiple `else` statements

• Using `if` followed by `else if` statements

• Using a `switch` statement

What does the `===` operator check for in a conditional statement?

• Only the value equality

• Only the type equality

• Both value and type equality

• Neither value nor type equality

Which of the following is a valid conditional statement that checks if `a` is not equal to `b`?

• `if (a != b) { }`

• `if (a =! b) { }`

• `if (a !== b) { }`

• Both A and C are correct

In the context of conditional statements, what does the `&&` operator represent?

• OR

• AND

• NOT

• XOR
