Question 1

T/F You can think of an array as a collection of variables contained within a single variable

Answer 1

True

Question 2

T/F You access an array element’s value just as you access the value of any other variable, except that you must include the element index in brackets

Answer 2

True

Question 3

T/F An if statement keeps repeating until its conditional expression evaluates to false

Answer 3

True

Question 4

T/F Case labels must be discrete values and cannot use operators

Answer 4

True

Question 5

T/F A break statement restarts a loop with a new iteration

Answer 5

False

Question 6

You use a(n) BLANK when you want to store a group or a list of related information in a single, easily managed location

Answer 6

array

Question 7

Each piece of data contained in an array is called a(n) BLANK

Answer 7

element

Question 8

The BLANK statement is used to execute specific programming code if the evaluation of a conditional expression returns a truthy value

Answer 8

if

Question 9

A set of statements contained within a set of braces is known as a(n) BLANK block

Answer 9

command

Question 10

If you want to execute one set of statements when a condition evaluates to a truthy value and another set of statements when the condition evaluates to a falsy value, you need the BLANK statement

Answer 10

if/else

Question 11

The BLANK statement controls program flow by executing a specific set of statements, depending on the value of an expression

Answer 11

switch

Question 12

A(n) BLANK label in a switch statement represents a specific value and is followed by one or more statements that are executed if the value of the label matches the value of the switch statement’s expression

Answer 12

case

Question 13

A case label consists of the keyword case, followed by a literal value or variable name, followed by a(n) BLANK

Answer 13

colon

Question 14

The BLANK label contains statements that execute when the value returned by the switch statement does not match a case label

Answer 14

default

Question 15

A(n) BLANK statement is used to end the execution of a switch statement

Answer 15

break

Question 16

The conditional expression in the while statement is enclosed within BLANK following the keyword while

Answer 16

parentheses

Question 17

A BLANK statement is a control flow statement that repeatedly executes a statement or series of statements while the value of a specific condition is truthy or until the value of a specific condition becomes truthy

Answer 17

loop

Question 18

One of the simplest types of loops statements is the BLANK statement, which repeats a statement or series of statements as long as a given conditional expression evaluates to a truthy value

Answer 18

while

Question 19

Each repetition of a looping statement is called a(n) BLANK

Answer 19

iteration

Question 20

Unlike the while statement, the statements in a(n) BLANK statement always executes once, before a conditional expression is evaluated

Answer 20

do/while

Question 21

The BLANK statement is used to repeat a statement or series of statements as long as a given conditional expression evaluates to a truthy value

Answer 21

for

Question 22

A(n) BLANK statement restarts a loop with a new iteration

Answer 22

continue

Question 23

A single statement that declares a variable and specifies array values as its content is called a(n) BLANK

Answer 23

array literal

Question 24

Changing the order in which JavaScript code is executed is known as

Answer 24

controlling flow

Question 25

To end a switch statement once it performs its required task, include a(n) BLANK statement at the end of the statements associated with each case label

Answer 25

break

Question 26

In a(n) BLANK loop, a loop statement never ends because its conditional expression is never falsy

Answer 26

infinite

Question 27

Each repetition of a looping statement is called a(n) BLANK

Answer 27

iteration

Question 28

Placing one decision-making statement within another decision-making statement creates a(n) BLANK decision-making structure

Answer 28

nested
