- 8. Functional Programming ● JavaScript allows us to assign functions into variables. ● JavaScript allows us to pass the functions as arguments. ● JavaScript allows us to define anonymous functions and supports closure. var f = function(){ //do something... }
- 9. JavaScript Libraries ● The true power of JavaScript is the huge number of available JavaScript libraries we can use in our code.
