# Using Lodash in Unqork

## Overview

Put simply, Lodash is a JavaScript library of functions. You can use these functions to complete common tasks in Unqork. You'll write Lodash as a formula with parameters relative to the function you decide to use. For example, `_.set` is a Lodash function that accepts three parameters to set a new object value.

### Where to Use Lodash in Unqork

Unqork lets you use Lodash anywhere you write formulas. For example, you can use Lodash in a [Calculator](/v1/docs/calculator-component) component or [Decisions](/v1/docs/decisions-component) component. You can also use Lodash in any of the formula operators in a [Data Workflow](/v1/docs/data-workflow-component).

Let's say you want to use a Calculator component to set key/value pairs in an object. You can use the `_.set` Lodash function from earlier to set the value and path of your object. To do this, you'll write the function as an output formula in your Calculator component.

### Writing Lodash Functions

Before you write your Lodash function, determine which function to use by visiting the function library documentation here: [https://lodash.com/docs/4.17.15](https://lodash.com/docs/4.17.15).

Writing Lodash in Unqork differs from how you write it elsewhere. Typically, Lodash functions start with a `_.` followed by the function name and its parameters. In Unqork, you'll write Lodash formulas as follows: `=LODASH("method", parameter 1, parameter 2)`.

Here's a breakdown of each part of the formula:

| **Part of Formula** | Description |
| --- | --- |
| **=LODASH** | Tells Unqork you're using a Lodash-type function. |
| **"method"** | Declares which Lodash function you're using. You must write your functions in camelCase between double-quotes. > [!NOTE] > When copying and pasting double-quotes, confirm they are not stylized. Adding stylized double-quotes might result in an error. |
| **parameter 1, parameter 2** | Declares the parameters of the function you're using. You must write these parameters in the same order as the Lodash documentation referenced above. > [!NOTE] > If your parameter uses a hard-coded value, you'll enter it between double-quotes. If your parameter references a variable, quotes are not necessary. |

Apply your formula to a Lodash function. Let's return to the example from earlier for setting key/value pairs in an object. Looking at the Lodash library, it's written as `_.set(object, path, value)`. In your Unqork formula, you'll modify the formula as `=LODASH("set", object, path, value).`
