Please modify the following javascript so that instead of displaying in the console, it displays on a webpage.

// Assign person's age to myAge variable

let myAge = 30;

// Assign value 2 to earlyYears variable

let earlyYears = 2;

// Multiply earlyYears by 10.5 and reassign it to earlyYears

earlyYears *= 10.5;

// Calculate laterYears by subtracting 2 from myAge

let laterYears = myAge - 2;

// Multiply laterYears by 4

laterYears *= 4;

// Add earlyYears and laterYears and assign it to myAgeInDogYears

let myAgeInDogYears = earlyYears + laterYears;

// Assign person's name to myName variable and convert it to lowercase

let myName = 'John'.toLowerCase();

// Output the result

console.log(`My name is ${myName}. I am ${myAgeInDogYears} years old in dog years`);
