Explain the use cases for, and differences between — bind, apply and call.

this gets pretty in-depth depending on your level of understanding of the concept of in JavaScript.

assuming that you fully understand that:

will bind to an object of your choice, even when it is called outside of that context (where it was first defined in some method on a different object). it is used for a later callback (as you create a new variable to bind).

this week was more about bringing together all of 411 in one big project, and even bringing a lot of things back from 311 (like debugging, minifying, npm folder structure, etc.) and lighting them in the context of actual front-end development. i definitely learned a lot about redux in the process of tying together our final project (other than the capstone).

in redux, this is where your state, reducers, and middleware are combined. for example:

import { createStore } from 'redux'

What is the meaning of “single source of truth” in Redux?

in redux, single source of truth refers to the global state that results from its proper implementation (i.e. a decent amount of boilerplate, which is definitely worth it if you find yourself struggling with your app’s state in a given framework). state can now be passed around and manipulated (reused) across components as props.

  • How does hoisting work in JavaScript?

hoisting is a mechanism of JavaScript whereby function declarations are moved to the top of their scope before code execution. this means that you can declare a function after you invoke it in your script. consider the following:

hoisted() // logs "poop"

function hoisted() {

this only applies to function declarations, so the following (function expression) would avoid this potential issue:

unHoisted() // returns undefinedconst unHoisted = () => {

What is in React? Explain its purpose.

is the method React runs in order to create and display valid HTML elements (first, it renders into a React element, and then it renders into a standard HTML element) in the browser. it first builds the code into its virtual DOM and then interpolates it back to the browser’s native DOM through the single element,
and every time that is invoked, React’s virtual DOM runs only the minimal JavaScript necessary to update whatever the author decides is important, while staying on the single .html file/page, . this means…

Can you explain the purpose of each type of HTTP Request when using a RESTful web service?

Create: this is the POST method, and allows users to add to an API
Read: this is your GET method, and allows users to simply “read” data
Update: this is your PUT method, and allows users to update info
Delete: this is your DELETE method, and allows users to delete info (or oftentimes pseudo-delete since rarely do websites/apps actually forego free user information, and it’s possible the user wants to reactivate their account)
