Tests:

Lodash get
_.get(person, 'name');
Native
person.name;
Nested (lodash)
_.get(person, 'level1.level2.level3');
Nested (native, dot)
person.level1.level2.level3;
Nested (optional chaining)
person?.level1?.level2?.level3;
Nested (custom implementation)
getByPathCustom(person, 'level1.level2.level3');
Non-existent (optional chaining)
person?.level1?.level2?.level3?.nonExistent?.foo
Non-existent (lodash)
_.get(person, 'level1.level2.level3.nonExistent.foo');
Non-existent (custom implementation)
getByPathCustom(person, 'level1.level2.level3.nonExistent.foo');
No path (lodash)
_.get(person, '');
No path (custom)
getByPathCustom(person, '');
Not nested (custom)
getByPathCustom(person, 'name');
Top level dot notation key (lodash)
_.get(person, 'dot.notation.key');
Top level dot notation key (custom)
getByPathCustom(person, 'dot.notation.key');
