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.

Lodash Methods

Description

_.castArray()It is used to cast value into an array if it is not an array.
_.clone()It is used to create a shallow copy of the value.
_.cloneDeep()It is used to create a deep copy of the value.
_.cloneDeepWith()It is used to clone value in a recursive way.
_.cloneWith()It is used to create a shallow copy of the value.
_.conformsTo()It is used to check if the given object conforms to the given source.
_.eq()It is used to find the two values are equivalent or not by performing the SameValueZero comparison.
_.gt()It is used to find the value is greater than other or not.
_.gte()It checks whether the specified value is greater than or equal to other or not.
_.isArguments()It checks if value is likely an arguments object.
_.isArray()It checks if the given value can be classified as an Array Value or not.
_.isArrayBuffer()It checks if the given object or value can be classified as an ArrayBuffer Value or not.
_.isArrayLike()It checks if the value is Array-like.
_.isArrayLikeObject()It checks the given value is an Array-like Object or not.
_.isBoolean()It checks if the given value can be classified as Boolean value or not.
_.isBuffer()It checks if the given value is Buffer or not.
_.isDate()It checks if the given value can be classified as Date Object or not.
_.isElement()It checks whether the specified value is a DOM element or not.
_.isEmpty()It checks if the value is an empty object, collection, map, or set.
_.isEqual()It performs a deep comparison between two values to determine if they are equivalent.
