A simple way to get and set object properties using paths (aka dot notation) with TypeScript support

const pathSplitRegexp = /(?<!\(.*)\.|(?<=.*\))\./g;
const parMatchRegexp = /[()]/g;

            .map((subpath) => subpath.replace(parMatchRegexp, ''));
        return { current, nested };
    },
    updateDeep: (parent, path, rest, value, force = false) => {
        const nestedProp = rest.shift();
        const hasPathProperty = Object.prototype.hasOwnProperty.call(parent, path);
        const hasPathObject = hasPathProperty && typeof parent[path] === 'object';
        const hasPathObjectSubPath = hasPathObject
            && Object.prototype.hasOwnProperty.call(parent[path], nestedProp);
        if (!nestedProp && (hasPathProperty || force)) {

            return true;

        const parsedSubpath = subpath.replace(parMatchRegexp, '');
        const isScopeObject = currentScope.value && typeof currentScope.value === 'object';
        const hasNotSubpath = !isScopeObject
            || !Object.prototype.hasOwnProperty.call(currentScope.value, parsedSubpath);
        if (hasNotSubpath)
            return true;
        currentScope.value = currentScope.value[parsedSubpath];
        return false;
    },
};
const has = (object, path) => {
    const currentScope = { value: object };
    return !path
        .split(pathSplitRegexp)
        .some((subpath) => helpers.analyzeSubpath(currentScope, subpath));
