Failing to load custom vailla js using hooks for POS

[MoSamir]

Following @kolate_sambhaji example:

How we can include js in particular page?

@vaibhavk Check following code. You can easily include your own js. You can also override existing feature using javascript prototype. @fahimalizain In this case, you need page_js hook instead on doctype_js

I have edit it to be:

erpnext.pos.PointOfSale = erpnext.pos.PointOfSale.extend({
    Array.from(document.getElementsByClassName('num-row')).slice(0, 3).forEach(x => {
        x.classList.add('hidden')
    })
})

Yet, Nothing happened.
