* Helper util to return a value from a certain path of the object.
* Path is specified as either:
* - a string of properties, separated by dots, for example: "x.y".
* - an array of properties, for example `[ 'x', 'y' ]`.
* You can also specify a default value in case the result is nullish.
*
* @param {Object} object Input object.
* @param {string|Array} path Path to the object property.
* @param {*} defaultValue Default value if the value at the specified path is undefined.
* @return {*} Value of the object property at the specified path.
