error (checkPropTypes is not a function) while using with sveltekit

[code-masala]

    import * as PropTypes from "prop-types";
    const {checkPropTypes, number} = PropTypes;
       const propTypes = {
        threshold: number,
    };
    checkPropTypes(propTypes, $$props, "prop", "Observer");

This is giving error checkPropTypes is not a function

import * as is almost never what you want; this is a CJS package so I’d suggest instead import PropTypes from ‘prop-types’, and then PropTypes.checkPropTypes.
