Learn JavaScript from Scratch JavaScript for Everyone - Random Numbers

The video tutorial explains how to generate random numbers using JavaScript's Math.random function. It covers generating numbers between 0 and 1, extending this to a range between 0 and 100, and using Math.floor to round numbers to the nearest whole number. The tutorial also demonstrates creating random numbers within a custom range, such as 0 to 83, and emphasizes the importance of these techniques for a final project.

What does the Math.random function return?

• A number between 0 and 1

• A number between 0 and 100

• A number between 1 and 100

• A number between 0 and 10

How can you generate a random number between 0 and 100 using Math.random?

• By adding 100 to Math.random

• By multiplying Math.random by 100

• By subtracting 100 from Math.random

• By dividing Math.random by 100

What is the purpose of using Math.floor with Math.random?

• To generate a number between 1 and 100

• To generate a number between 0 and 1

• To round the number up to the nearest whole number

• To round the number down to the nearest whole number

How can you generate a random number between 0 and 83?

• By multiplying Math.random by 83

• By adding 83 to Math.random

• By dividing Math.random by 83

• By subtracting 83 from Math.random

What is the difference between Math.floor and Math.ceil?

• Both round to the nearest decimal

• Math.floor rounds down, Math.ceil rounds up

• Math.floor rounds up, Math.ceil rounds down

• Both round to the nearest whole number
