 ### Type Conversion
 
-In order to be able to dynamically convert the type of a value during evaluation - both explicit conversion ( intentional "casting" ) or implicit conversion ( automatic coercion ) - will use the same mechanism.
-E.g. If the value is and `object` and the operations requires a `primitive` output, it'll look for the appropriate method [toPrimitive](http://www.ecma-international.org/ecma-262/6.0/#sec-toprimitive) which will convert its input argument to a non-Object type. If an object is capable of converting to more than one primitive type, it may use the optional hint PreferredType to favour that type. If it's a `primitive` and an `object` is needed, it'll call the [ToObject](http://www.ecma-international.org/ecma-262/6.0/#sec-toobject) abstract operation in order to perform the required transformation and eventually return a [Primitive wrapper object](https://developer.mozilla.org/en-US/docs/Glossary/Primitive#Primitive_wrapper_objects_in_JavaScript) aka [Boxing Wrapper](https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/types%20%26%20grammar/ch3.md#boxing-wrappers).

-Several things might go wrong during this conversion and all the cases are captured on the spec, but since specs, sometimes are hard to follow, I'd love to show you some practical examples from [YDKJS: Types & Grammar - Natives](https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/types%20%26%20grammar/ch3.md#chapter-3-natives)

 Since implicit conversion, called **coercion** is one of the most misunderstood characteristics of JavaScript, let's have a read at [YDKJS: Types & Grammar - Coercion](https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/types%20%26%20grammar/ch4.md#chapter-4-coercion)
