Lodash

What is Lodash ?

Lodash is a JavaScript library that works on the top of underscore.js. It helps in working with arrays, strings, objects, numbers, etc. It provides us with various inbuilt functions and uses a functional programming approach which that coding in JavaScript easier to understand because instead of writing repetitive functions, tasks can be accomplished with a single line of code. It also makes it easier to work with objects in JavaScript if they require a lot of manipulation to be done upon them.
