Please [post questions on Stack Overflow](https://stackoverflow.com/questions/ask). You can open issues with questions, as long you add a link to your Stack Overflow question. 2. For bug reports and feature requests, open issues. :bug: 3. For direct and quick help, you can [use Codementor](https://www.codementor.io/johnnyb). :rocket: ## :memo: Documentation ### `Typpy(input, target)` Gets the type of the input value or compares it with a provided type. Usage: ```js Typpy({}) // => "object" Typpy(42, Number); // => true Typpy.get([], "array"); => true ``` #### Params - **Anything** `input`: The input value. - **Constructor|String** `target`: The target type. It could be a string (e.g. `"array"`) or a constructor (e.g. `Array`). #### Return - **String|Boolean** It returns `true` if the input has the provided type `target` (if was provided), `false` if the input type does *not* have the provided type `target` or the stringified type of the input (always lowercase). ### `Typpy.is(input, target)` Checks if the input value has a specified type. #### Params - **Anything** `input`: The input value. - **Constructor|String** `target`: The target type. It could be a string (e.g. `"array"`) or a constructor (e.g. `Array`). #### Return - **Boolean** `true`, if the input has the same type with the target or `false` otherwise. ### `Typpy.get(input, str)` Gets the type of the input value. This is used internally. #### Params - **Anything** `input`: The input value. - **Boolean** `str`: A flag to indicate if the return value should be a string or not. #### Return - **Constructor|String** The input value constructor (if any) or the stringified type (always lowercase). ## :yum: How to contribute Have an idea? Found a bug? See [how to contribute][contributing]. ## :sparkling_heart: Support my projects I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications *for free*! You can even change the source code and redistribute (even resell it). However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it: - Starring and sharing the projects you like :rocket: - [![Buy me a book][badge_amazon]][amazon]—I love books! I will remember you after years if you buy me one. :grin: :book: - [![PayPal][badge_paypal]][paypal-donations]—You can make one-time donations via PayPal. I'll probably buy a ~~coffee~~ tea. :tea: - [![Support me on Patreon][badge_patreon]][patreon]—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone). - **Bitcoin**—You can send me bitcoins at this address (or scanning the code below): `1P9BRsmazNQcuyTxEqveUsnf5CERdq35V6`  Thanks! :heart: ## :dizzy: Where is this library used?
