## Overview
The **`_.isEmpty()` method** in Lodash checks if a value is empty. 

## Syntax
```
_.isEmpty(value)
```

## Parameters
This method accepts the following parameters:
* **`value`**: This is the value to be checked.

## Return value
This method returns `true` if the value is empty, and vice-versa.

If the value is a `boolean` or `null`, it will always return `true`.

If the value is a `collection`, this method will evaluate its length to determine if it's empty. 

## Example
Let’s look at an example of the `_.isEmpty()` method in the code snippet below:


// a null value
const value1 = null

// a boolean value
const value2 = true

// an empty array
const value3 = []

// a non-empty array
const value4 = [1, 2, 3]

// check if above values are empty and print on console
console.log('value1 is empty check:', _.isEmpty(value1));
console.log('value2 is empty check:', _.isEmpty(value2));
console.log('value3 is empty check:', _.isEmpty(value3));
console.log('value4 is empty check:', _.isEmpty(value4));

## Explanation
In the HTML tab:
* **Line 5**: We import the `lodash` script.

In the JavaScript tab:
* **Line 2**: We create a variable `value1` and initialize it with `null`.
* **Line 5**: We create a variable `value2` and initialize it with `true`.
* **Line 8**: We create an empty
array `value3`. 
* **Line 11**: We create an 
array `value4` and initialize it with a few values.
* **Lines 14-17**: We use the `_.isEmpty()` method to check if the values are empty. Also, we print the output on the console.

## Output
* The variable `value1` is `null`. Therefore, `_.isEmpty()` returns `true`.
* The variable `value2` is a boolean. Therefore, `_.isEmpty()` returns `true`.
* The variable `value3` is an empty array. Therefore, `_.isEmpty()` returns `true`.
* The variable `value4` is a non-empty array. Therefore, `_.isEmpty()` returns `false`.


What is the _.isEmpty() method in Lodash?

The _.isEmpty() method in Lodash checks if a value is empty, returning true for empty collections, null, and booleans.
