Math.floor(Math.random() *10)

The code Math.floor(Math.random() * 10) can be broken down into the following steps:

1. Math.random(): This function generates a random decimal number between 0 (inclusive) and 1 (exclusive). For example, it may generate a number like 0.785.

2. Math.random() * 10: This step multiplies the random decimal number generated in step 1 by 10. The result will be a random decimal number between 0 (inclusive) and 10 (exclusive). For example, if the random number generated in step 1 is 0.785, then the result of this step would be 7.85.

3. Math.floor(): The Math.floor() function takes a decimal number as input and rounds it down to the nearest whole number. For example, if the result of step 2 is 7.85, then Math.floor(7.85) would give us 7.

Putting it all together, the code Math.floor(Math.random() * 10) generates a random whole number between 0 (inclusive) and 9 (inclusive).
