Clamp fails if element style is undefined

Title says it all.

Uncaught TypeError: Cannot read property 'webkitLineClamp' of undefined
    at clamp (clamp.js:32)

You must pass a single element

I think he has modified the script, the script check the browser can use webkitLineClamp or not, so that is this error confused...

you can forEach element array
elementArray.forEach(x => {
$clamp(x, { clamp: 2 })
});
but I think the performance is bad
