How to set value of select with node Puppeteer

I found a solution myself:

async function setSelectVal(sel, val) {
    page.evaluate((data) => {
        return document.querySelector(data.sel).value = data.val
    }, {sel, val})
}

await setSelectVal('#select_id', 'newValue')

You can use page.select() to select an option:

await page.select('select#example', 'carrot');
