@satyasrisundarapalli Please make the necessary changes to README file too

[satyasrisundarapalli]

1. In the READMDE.md there are no one-line descriptions for the two functions against their anchor tags.
2. The function descriptions do not follow the standard format given in the README file. There are several inconsistencies like no proper tables and good examples demonstrating the funciton's use.
3. There are changes being made to package.json which are not necessary. Stringzy is added there as a dependency.

Hi @satyasrisundarapalli , there are some minor inconsistencies in the README file. The format is not the same as other utility definitions in the file. Also there is some changes made in the pacakage.json and package-lock.json.
These 2 are the only fixes you need to make.

Looking forward to merging your PR!
