A JavaScript utility library for both server and browser

/**
 * Get a value by dot-separated path or key array from a collection
 * Does not support '[i]', e.g. 'a[0].b.c' style accessor, use [ 'a',  0, 'b', 'c' ] instead, different from lodash/get
 * @alias object.get
 * @param {Object} collection - The collection
 * @param {string|array} keyPath - A dot-separated path (dsp) or a key array, e.g. settings.xxx.yyy, or ['setting', 'xxx', 'yyy']
 * @param {Object} [defaultValue] - The default value if the path does not exist
 * @returns {*}
