- Q1. What is the difference between normal and arrow functions
- Ans.
Arrow functions are more concise and have a lexical 'this' binding compared to normal functions.
Arrow functions do not have their own 'this' keyword, they inherit it from the parent scope.
Arrow functions do not have their own 'arguments' object.
Arrow functions cannot be used as constructors with 'new'.
Arrow functions are more concise and have implicit return when no curly braces are used.

- Q3. They asked to show me an example using the API call
- Q4. Difference between forEach and Map
- Ans.
forEach is used to iterate over an array and perform a function on each element, while map creates a new array by applying a function to each element.
forEach does not return a new array, while map does
forEach does not modify the original array, while map creates a new array
forEach is used for side effects, while map is used for transformation
Example: forEach - array.forEach(item => console.log(item)), map - const newAr
