TypeScript for Beginners - Array of Arrow Functions

The video tutorial explains how to create and use arrow functions in JavaScript. It starts by introducing the concept of arrow functions and demonstrates how to create an array to store these functions. The tutorial then walks through the process of defining anonymous functions using a for loop and adding them to the array. It explains the syntax of arrow functions, including parameters, return types, and the arrow symbol. Finally, the tutorial shows how to invoke these functions and display their output using console.log, resulting in a sequence of numbers from 0 to 9.
