Web Design - JavaScript 1 with correct
answers 100% 2025
Use of JavaScript - Correct Answer When you create HTML documents, you'll almost always add
behavior to make the document more interactive. You might want to enable some HTML elements to
perform actions. Maybe you want to add a fast and fully-featured auto-completion menu to your search
box displaying results "as you type".
Understanding JavaScript (JS) - Correct Answer - Using expressions to produce data
- Using statements
- Working with functions
- Browser's built-in alert, prompt, and confirm functions
- Using variables
- Conditional programming
- Implementing code loops
JavaScript is... - Correct Answer a programming language that mainly is used in the design of the user
interface of web applications. JavaScript is normally executed (interpreted) by a web browser. JavaScript
is not related to Java, although it is a curly-brace language like Java.
JavaScript is dynamically typed... - Correct Answer which means that when you create a variable, you
don't need to specify its type.
JS variables are... - Correct Answer used to store data and they can hold a value of any data type.
var msg = 'Hello world'; // msg is a string variable and its value is Hello world
var num = 10.3 // num is a numeric variable and its value is 10.3 - Correct Answer var is one of the many
JS keywords. You will use it to declare and initialize variables. msg and num are names of variables or
identifiers.
Identifiers are... - Correct Answer case sensitive and should always start with a letter, and underscore
(_), or a dollar sign ($). Hyphens are not allowed; they are reserved for subtractions only.
, When you want to create a program, you typically find that the program must access and manipulate
data because data is at the root of all systems. - Correct Answer You collect data, manipulate data, store
data, retrieve data, display data, and so on.
Most data can be broken into smaller pieces called values. - Correct Answer JavaScript defines a value
type as an object, a primitive value, or a function.
An object is... - Correct Answer a collection of properties, and a property is an association between a
name (key) and a value. A property's value can be a function, in which case the property is known as a
method. Examples of objects could be a person, an animal, an HTML document, etc.,; anything that can
have properties with values.
Primitive value - Correct Answer is a data that is represented at its lowest level of the language
implementation and, in JavaScript, is one of the following types: undefined, null, Boolean, number, or
string.
A function is... - Correct Answer a callable object, and a function that is a member of an object is called
a method.
JavaScript also defines the following built-in objects: - Correct Answer the global object, the Object
object, the Function object, the Array object, the String object, the Boolean object, the Number object,
the Math object, the Date object, the RegExp object, the JSON object, and several variations of Error
objects.
An expression is... - Correct Answer a piece of code that produces a value.
An expression can be a simple value, or it can contain operands and operators. - Correct Answer
Mathematical symbols, such as the plus, minus, divide, and multiply signs, are examples of operators.
Numbers are operands. The operators cause an operation to be executed by using the operands on each
side of the operator. Note that an operand can be a value, or it can be another expression.
7 + 3 * 8 - Correct Answer This is an expression with operands and operators. The numbers are
operands. The operators cause an operation to be executed, using the operands on each side of the
operator.
