how to use the spread function from lodash in javascript

The spread function from lodash is a utility function that allows you to quickly and easily merge two or more arrays into a single array. Here's how you can use it in Javascript:

index.tsx
const _ = require('lodash');

const arr1 = [1, 2, 3];
const arr2 = [4, 5, 6];
const arr3 = [7, 8, 9];

const mergedArr = _.spread([...arr1, ...arr2, ...arr3]);

console.log(mergedArr); // Output: [1, 2, 3, 4, 5, 6, 7, 8, 9]

In the above code, we first import the lodash library and define three arrays that we want to merge. We then use the spread operator to expand each array into its individual elements and then pass those elements as arguments to the _.spread() function. This function takes in an array of arguments and applies them to a given function. In our example, the _.spread() function applies the elements of the three arrays to the Array.prototype.concat() function, which merges them into a single array.

Finally, we log the merged array to the console, which outputs the following: [1, 2, 3, 4, 5, 6, 7, 8, 9].
