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