Arguments

bankLoan.calcPayments(60); Which is the Argument in this statement?

It is a basic method used to write text to the console.

console.log()

It is where messages are displayed that are invisible to users and are separated from the HTML/CSS environment. However, this can be visible in a browser’s developer tool console.

Console

This method is used to display an alert box that has amessage and an OK button. The text in the argument is the information users are forced to see, so it is better not to overuse this method.

alert()

Which is the correct syntax for console.log?

console.log("Hello, World!");

Which is the correct syntax for alert()

It is used to perform specific actions on arguments called operands, which can be both values and variables.

JavaScript Operator

operators allow assigning of values to variables and constants. It commonly uses the equal sign (=).

Assignment

operators express mathematical operations and accept numerical values and variables. It includes addition, subtraction, multiplication, division, remainder, power, and increment that adds one (1) in the operand and decrement (--) that subtracts one (1).

Arithmetic

operators work with Boolean-type values such as true or false. It includes a conjunction that performs logical AND (&&), an alternative that performs logical OR (||), and a negation that performs logical NOT (!).

Logical

operators compare two (2) variables or operands. It includes not equal or equal to the value of the variable or operand (!=, ==), equal value and equal type (===), less than and greater than (<, >), and less than or equal to and greater than or equal to (<=, >=),

Comparison

It is the value that the program stores in a computer’s memory. It is used by writing a statement first that creates the variable and assigning a name for it.

JavaScript Variable

The assigned name to a variable is called what?

identifier

Which statement is NOT TRUE about JavaScript naming conventions?

It must include spaces.

These are unique words that are already part of the JavaScript language syntax.

Keywords or reserved words

"It represents textual data." What data type is being described?

String

"It contains a logical entity that may return a TRUE or FALSE value." What data type is being described?

Boolean

"Any digit that is either an integer or a decimal." What data type is being described?

Number

"an unknown or missing value." What data type is being described?

Null

"refers to a variable with no value." What data type is being described?

Undefined

Which is NOT a JavaScript data type?

Decimal

Which is the correct syntax for declaring variables in JavaScript?

let taxRate = 0.05;

This is used to declare a set of data represented by a single variable name.

Array

Which is the correct syntax in creating an Array?

let months = ["Jan", "Feb", "Mar", "Apr", "May",];

It breaks up the execution flow using decision-making, branching, and looping to enable programs to conditionally execute specific code blocks.

Control flow

It is the simplest control flow instruction in JavaScript. It checks a given condition and, depending on its Boolean value, either executes a code block or skips it. The code block should be separated using curly brackets.

If statement

Which is the correct syntax for an If statement?

if (isUserReady) { alert("User is ready!"); }

Which is the correct syntax in an If...else statement?

if (isUserReady) { console.log("User is ready!"); } else { console.log("User is not ready!"); }

This keyword is an optional part of the if statement, and it allows the addition of a second code block that will be executed only when the initial condition is NOT met.

else

if (number < 20) { alert("Less than 20"); } else if (number < 40) { alert("Less than 40"); } else if (number < 60) { alert("Less than 60"); } else { alert(">100") }

These are the second form of control flow statement. While control flow statements can change code behavior, loops are an easy way to repeat any fragment of the code as many times as possible, or until a stopping condition is met.

Loops

It is where a code block is executed while a given condition is true but stops once the condition is false.

While loop

In a loop, when a code block is repeated, it is referred to as an?

Iteration

This is avoided by including at least one statement that eventually results in a false value for the condition.

Infinite loop

A code block uses this, whose value changes with each iteration, and once that counter fails to match the condition, the loop ends.

Counter

Which is the correct syntax for a While loop?

let j = 1; while (j <= 5) { document.write(j + "<br>"); j++; }

It is used to loop the statement until it evaluates to false. It evaluates a condition after executing the command block at least once.

Do while loop

In the parentheses after the word for, there will be no single condition this time, unlike in the while loop. Here, it is divided into three fields by semicolons, and each field is assigned a different meaning.

For Loop

Which statement is NOT TRUE about For Loop syntax?

The third expression cannot be left empty.

Which is the correct syntax for a for loop?

for (let i = 5; i < 31; i++) { console.log(i); }
