Question 1

A(n)____ statement is a statement that returns a value to the statement that called the function.&#10;A) return&#10;B) replace&#10;C) value&#10;D) exit

Accepted Answer

A return statement is used in a function to return a value to the statement that called the function. It is the only choice that fits the given definition.

Question 2

A ____ variable is one that is declared outside a function and is available to all parts of your program.&#10;A) local&#10;B) limited&#10;C) scoped&#10;D) global

Accepted Answer

A global variable is accessible from any part of the code and is declared outside of any function. Local variables are declared inside a function and are only accessible within that function, limited variables and scoped variables are not commonly used programming terms.

Question 3

Programming languages that require you to declare the data types of variables are called ____ typed programming languages.&#10;A) dynamic&#10;B) strongly&#10;C) static&#10;D) loosely

Accepted Answer

B

Question 4

Data types that can be assigned only a single value are called ____ types.&#10;A) primitive&#10;B) null&#10;C) numeric&#10;D) Boolean

Accepted Answer

Primitive data types are the basic data types that can hold a single value, such as int, char, and float in many programming languages.

Question 5

You can use the compound ____ to combine two strings.&#10;A) value separator&#10;B) equals comparison&#10;C) assignment operator&#10;D) declaration operator

Accepted Answer

The assignment operator (=) is used to assign a value to a variable. It can also be used to combine two strings by assigning the concatenation of the strings to a new variable. For example, "hello " + "world" can be combined using the assignment operator as follows:

new_string = "hello " + "world"

This assigns the value "hello world" to the variable new_string.

Question 6

In JavaScript programming, you can write your own procedures, called ____, which refer to a related group of JavaScript statements that are executed as a single unit.&#10;A) programs&#10;B) functions&#10;C) modules&#10;D) objects

Accepted Answer

The correct term for a group of related JavaScript statements that are executed as a single unit is a function. A program refers to a larger set of instructions, modules refer to separate pieces of functionality that can be imported and exported between different files, and objects refer to a combination of data and functions that represent a specific entity or concept.

Question 7

Parentheses are used with expressions to change the associativity with which individual operations in an expression are evaluated.

Accepted Answer

Parentheses can be used to override the default order of operations and change the associativity in an expression.

Question 8

A logical operator is used to compare two string operands for equality.

Accepted Answer

Logical operators are used for boolean operations such as AND, OR, and NOT. They are not used to compare string operands for equality. String comparison operators such as "equals" or "not equals" are used for this purpose.

Question 9

In JavaScript code, you use the words yes and no to indicate Boolean values.

Accepted Answer

The correct way to indicate Boolean values in JavaScript is by using the keywords true and false. The words "yes" and "no" are not recognized as Boolean values in JavaScript.

Question 10

The strict equal operator is ____.&#10;A) =&#10;B) ==&#10;C) ===&#10;D) !=

Accepted Answer

The strict equal operator is represented by === and it checks for equality of both value and type. This means that if two values are not of the same type, it will return false even if their values are the same. This operator is commonly used in JavaScript to avoid unexpected type coercion.
