how to use the head function from the underscore library in javascript

head is a function in the Underscore library that returns the first element of an array. Here's how to use it:

index.tsx
// First, make sure you have included Underscore in your project:
// <script src="underscore.js"></script>

// Then, create an array to test the function:
var myArray = [1, 2, 3, 4, 5];

// Use the head function to get the first element of the array:
var firstElement = _.head(myArray);

// Log the result to the console:
console.log(firstElement); // Output: 1
362 chars
12 lines

In this example, we created an array called myArray, and passed it to the head function. The function returned the first element of myArray (which is 1), and we stored it in the firstElement variable.

Finally, we logged the result to the console using console.log().
