You can get lodash from GitHub repository , cdnjs or via NPM . Once done you can include a reference in your HTML.
A simple example of the power of lodash is this snippet of code which is looping through a shared Kendo datasource that is being used in large Kendo grid. The shared datasource has many duplicates and this snippet does four things:
- Removes duplicate account numbers
- Plucks out only the account numbers into a new array
- Sorts the array by alphabetical order
- Removes blank entries
Good example - Simple one line of TypeScript which would take many line of code without lodash
I created Lo-Dash to provide more consistent cross-environment iteration support for arrays, strings, objects, and arguments objects1. It has since become a superset of Underscore, providing more consistent API behavior, more features (like AMD support, deep clone, and deep merge), more thorough documentation and unit tests (tests which run in Node, Ringo, Rhino, Narwhal, PhantomJS, and browsers), better overall performance and optimizations for large arrays/object iteration, and more flexibility with custom builds and template pre-compilation utilities.
