The snippet shows every even number lower than ten by iterating through every number from 0-9 and checking if the number is divisable by two without a remainder using the modulo (%) operand.
It then creates a paragraph element for every such number, assigns the number as the text and appends the element to the document.
script.js
for (let i = 0; i < 10; i++) {
if (i % 2 === 0) {
const paragraph = document.createElement('p')
paragraph.innerText = i
document.body.appendChild(paragraph)
}
}
