javascript-lodashHow do I use Lodash to remove null values from an array in JavaScript?

Using Lodash to remove null values from an array in JavaScript is quite simple. Here is an example code block to demonstrate:

//Example array with null values
let array = [1, null, 2, 3, null, 4, 5];

//Using Lodash to remove null values
let filteredArray = _.without(array, null);

//Output
console.log(filteredArray); // [1, 2, 3, 4, 5]

The code above uses the Lodash without method to filter out any values that are null from the array variable. The output of the code will be a new array without any null values.

Code explanation

• let array = [1, null, 2, 3, null, 4, 5]: This is the array we will be filtering.
• let filteredArray = _.without(array, null): This is the Lodash without method, which takes two arguments. The first argument is the array we want to filter, and the second argument is the value we want to remove. In this case, we want to remove any values that are null.
• console.log(filteredArray): This will output the filtered array to the console.
