add ToQuery and FromQuery

[shayan0v0n]

The ToQuery() function is a powerful utility in Go that facilitates the effortless conversion of a map into a well-formed query string. This functionality becomes particularly valuable when you need to create query strings for web requests or other scenarios where structured key-value pairs are essential.

The ToQuery() function streamlines the process of transforming a map into a query string by intelligently handling the concatenation of key-value pairs. Let's delve into how this function simplifies the generation of query strings with a concrete example.

Consider the following scenario where you have a map representing user information:

map[email:joan@gmail.com token:jkbcqp1wu2b user:joan]

The desired output is a well-formatted query string:

user=joan&email=joan@gmail.com&token=jkbcqp1wu2b

Complementing the ToQuery() function, the FromQuery() function seamlessly reverses the process. It transforms a well-formed query string back into a map, providing a versatile bidirectional solution for scenarios requiring both query string creation and parsing.

user=joan&email=joan@gmail.com&token=jkbcqp1wu2b

ere, the FromQuery() function adeptly parses the query string, reconstructing the original map:

map[email:joan@gmail.com token:jkbcqp1wu2b user:joan]
