Here's my code:

const images = document.getElementsByTagName('img')
for (let i = 0; i < images.length; i++) {
    const currentImage = document.getElementById(`${i}`)
    currentImage.onload = () => {
        const flex = document.getElementById(`${i}`).clientWidth / document.getElementById(`${i}`).clientHeight
        console.log(flex)
        document.getElementById(`${i}`).style.flex = flex
    }
}

And the console.log statement always returns 0.75.
