querier.js v1.1.0

#Querier.js

The concept for this project was based off of C# Linq Query Syntax.

##Description

The objective of Querier.js is to simplify some of the work when dealing with multiple 'enumerable' objects.

##Usage

To use the Querier, depending what you're trying to do, you require to have certain methods.

Examples will be shown on both C#'s Linq and Javascript

By including Querier.js you automatically get .select, .selectMany and .where on Array.prototype

1. select: In order to use a single { as, from } clause, the Object you're trying to enumerate should have a 'select' method.

     var collection = Enumerable.Range(1, 3).ToList();
     ...
     from a in collection
     select a + 3

     let collection = [1, 2, 3];
     ...
     Querier
       .append({ as: 'a', from: collection })
       .select(({a}) => a + 3);

2. selectMany: In order to use several { as, from } clauses, the Object you're trying to enumerate should have a 'selectMany' method.

     var collection = Enumerable.Range(1, 3).ToList();
     ...
     from a in collection
     from b in collection
     from c in collection
     select a + b + c

     let collection = [1, 2, 3];
     ...
     Querier
       .append({ as: 'a', from: collection })
       .append({ as: 'b', from: collection })
       .append({ as: 'c', from: collection })
       .select(({a, b, c}) => a + b + c);

3. where: In order to use one or more { as, from, where} clause, the Object you're trying to enumerate should have a 'where' method.

     var collection = Enumerable.Range(1, 3).ToList();
     ...
     from a in collection
     where a % 2 == 0
   
     from b in collection
     where b % 2 != 0
   
     from c in collection
     select a + b + c

     let collection = [1, 2, 3];
     ...
     Querier
       .append({ as: 'a', from: collection, where: (a) => a % 2 === 0 })
       .append({ as: 'b', from: collection, where: (b) => b % 2 !== 0 })
       .append({ as: 'c', from: collection })
       .select(({a, b, c}) => a + b + c);

To Note: Even though I always used the parameters in the order I appended them, you can have them in any order you'd like. Say, instead of select({a, b, c}) you could have select({c, b, a}) and it would work the same, I had them in order because I like it organized that way.
