JavaScript JavaScript Numbers The Math Object Random Number Challenge – Solution

Wanted some feedback on my code.

My code works as intended but wondering if there was a better way to write it and if it's understandable? Is there anything I can do to improve?

// Collect input from a user

const userNumber = +prompt('please imput a number?');

// Convert the input to a number

// Use Math.random() and the user's number to generate a random number

const genNumber = Math.floor(Math.random() * userNumber) +1;

// Create a message displaying the random number

console.log(${genNumber} is a number between 1 and ${userNumber});

The unary + trick for numeric conversion has a slightly different behavior from parseInt, and perhaps is not as clear to someone reading the code.

Otherwise, everything looks pretty solid. :+1:
