Exploring Conditional Logic in p5.js

This video tutorial introduces conditional statements and Boolean expressions in p5.js. It explains how programs make decisions using Boolean logic and relational operators. The syntax for writing conditional statements is detailed, followed by a practical example involving mouse interaction to change a circle's color. Advanced relational operators are also discussed, providing a comprehensive understanding of how to implement conditional logic in programming.

What is the primary purpose of conditional statements in programming?

• To create loops

• To make decisions in code

• To define functions

• To store information

What happens if the Boolean expression in an if statement evaluates to false?

• The code inside the if block is executed

• The code inside the if block is skipped

• An error is thrown

• The program stops

In the example provided, what color does the circle turn when the mouse's x position is greater than 300?

• Red

• Purplish pink

• Blue

• Green

What is the purpose of indentation in an if statement block?

• To change the way the code runs

• To help visually organize the code

• To create a new variable

• To define a function

Which relational operator checks if a value is less than or equal to another value?

• ==

• <=

• >=

• !=

What does a single equals sign '=' represent in JavaScript?

• Logical AND

• Equality check

• Logical OR

• Assignment operation

Why is it generally not a good idea to test if the mouse is on an exact pixel?

• It causes errors

• It is better to check for ranges

• It is not precise

• It is too complex
