||
## Why Lodash?
|
||
|
||
Lodash makes JavaScript easier by taking the hassle out of working with arrays,<br>
|
||
numbers, objects, strings, etc. Lodash’s modular methods are great for:
|
||
|
||
* Iterating arrays, objects, & strings
|
||
* Manipulating & testing values
|
||
* Creating composite functions
|
||
|
||
## Module Formats

||
|
||
Lodash is available in a [variety of builds](https://lodash.com/custom-builds) & module formats.
