Star Wars JavaScript Challenge

What is the correct syntax for declaring a variable in JavaScript?

• variable myVariable;

• const myVariable = 5;

• let myVariable;

• myVariable = 10;

What is the purpose of using loops in programming?

• To slow down the program

• To execute a set of instructions repeatedly until a specific condition is met.

• To make the code more complicated

• To confuse other programmers

Can you write a Star Wars themed code to move a character across the screen?

• Hardcode the character's position without any dynamic updates

• Use a loop to update the character's position continuously on the screen.

• Use a random number generator to determine the character's movement

• Implement a Star Trek themed code instead

How do you define a function in JavaScript?

• functionName(parameters) { // code here }

• functionName(parameters) { // function body }

• functionName(parameters) { // logic here }

• function functionName(parameters) { // function body }

What is the importance of debugging in coding?

• Debugging slows down the coding process.

• Errors in the code should be left unresolved.

• Debugging is crucial for identifying and fixing errors in the code.

• Debugging is only necessary for advanced programmers.

Write a function in JavaScript to calculate the total score in a Star Wars game.

• function calculateTotalScore(scores) { return scores.reduce((total, score) => total + score, 0); }

• function getTotalScore(scores) { return scores.reduce((total, score) => total + score, 0); }

• function calculateScore(scores) { return scores.reduce((total, score) => total + score, 0); }

• function calculateTotal(scores) { return scores.reduce((total, score) => total + score, 0); }

Explain the concept of conditional statements in programming.

• Conditional statements have no impact on the execution of a program

• Conditional statements are used to format text in programming

• Conditional statements help control the flow of a program by executing different code blocks based on specified conditions.

• Conditional statements are only used in advanced programming languages

What are the different data types available in JavaScript?

• integer

• float

• string, number, boolean, null, undefined, object, symbol, bigint

• array

Solve the Star Wars coding challenge: Create a function to check if a character has enough health points.

• function validateHealth(health) { return health >= thresholdValue; }

• function checkCharacterHealth(health) { return health >= thresholdValue; }

• function checkPoints(health) { return health >= thresholdValue; }

• function checkHealthPoints(healthPoints) { return healthPoints >= thresholdValue; }

How can you use arrays in JavaScript to store multiple values?

• myArray = [value1, value2, value3];

• myArray = {value1, value2, value3};

• let myArray = [value1, value2, value3];

• array = {value1, value2, value3};
