Refactor remaining files in parser/utils

[prajwalkulkarni]

💫 Changelog

⭐ Improved typesafety in the remaining TS files located in parser/utils.
⭐ Changed var to let and const as applicable.
⭐ Added strict equality check
⭐ If the name of identifiers of key and value are the same, do not pass the value identifier explicitly. E.g: Instead of using atoms.push({x:x,y:y}) simply use atoms.push({x,y})
