Added new methods and fixed breaking moment simple format test case

[shubhamV123]

Following items in these commits :

1. Added lodash get function
2. new Intl.DateTimeFormat is not giving the date in which moment formatted the date which causes test failing. Fixed it. ** Solution **: Simply added vanilla date string interpolation

Hi @shubhamV123, thanks for your contribution.
I have to ask if you could isolate the new implementation from the moment fix: the latter has been tackled in another PR which uses a similar approach. I'd love to get the get implementation in 😊

@cedmax I can't push the code of because of that test failing that's why I have to add a fix for that code. Either you merge that code to master first. Then I will give you pull request again.

I see, ok I will look into it, thanks for letting me know

[shubhamV123]

Cool. Let me know once it's fixed. If required I will reraise pull request.

Hi @shubhamV123, I removed that test, if you merge master and choose it over your changes you should be able to push the new code without problems

[shubhamV123]

@cedmax Rebased my branch with upstream. Now you can merge with get code.

Thanks again
