Hi @sundriyalabhishek1330_b3a2c60b440c75c8,
In Javascript, functions can be assigned to variables in the same way that strings or arrays can. They can be passed into other functions as parameters or returned from them as well. A “higher-order function” is a function that accepts functions as parameters or returns a function .
