Example

import {
    createPointCB,
    getClientRect,
    pointInside
} from 'dom-plane';

const point = {};
const pointCB = createPointCB(point);

window.addEventListener('mousemove', pointCB);
window.addEventListener('mousedown', (e)=>{
    console.log('point is inside '+e.target, '=', pointInside(point, e.target))
    console.log('current rect ', getClientRect(e.target))
})

Exported functions.
