TheOdinProject

For the visual repository with access to live web pages, use GitHub pages.

The following repository contains my submissions for assignments in The Odin Project. Each section below includes a list of points that I've learned while studying its corresponding section in the curriculum. If there is a project associated with a section, a link to my submission will be included in the heading. There is also a list of links to all my project submissions under the "Projects" section.

Projects

HTML Foundations (Project: Recipes)

  • Google evaluates search terms in headers based on which rank of header is used (i.e. h1 more important than h2)
  • Image tags should always include an "alt" attribute to improve accessibility
  • Git commits should use an active voice (i.e. "Fix player collision bug" instead of "Fixed player collision bug") to match Git conventions

CSS Foundations

  • There are 5 types of selectors in CSS:
    • Universal (*)
    • Class (.class-name)
    • ID (#idname)
    • Grouping (.class-name, #idname, div...)
    • Element/Type (div, ul, body, etc.)
  • The CSS cascade is the most important concept of the language (hence, why it's part of the name) but also the hardest
    • Determines which styles are applied to any given element
  • The Box Model:
    • Everything you see on a webpage is either part of a box or a box itself
  • A box's size and its relationship to the content inside are determined by:
    • Padding (space between content and border)
    • Border (edge between padding and margin)
    • Margin (space between elements; margins have the ability to collapse or overlap between elements)

Flexbox (Project: Landing Page)

  • How to use Flexbox:
    • Slap on a "display: flex;" and "flex-direction: column;" style
    • Call it a day
  • Jokes aside, Flexbox is powerful but deceptively simple
  • "display: flex;" is for flex containers, "flex: ...;" is for flex children
  • Flexbox can be easily applied to lists for a simple navbar
  • Making things stretch on the page is easy with "max-width: x%;" and "width: 100%"
    • This will force it to cover the specified percentage of the page horizontally
  • Many predefined HTML tags have default margins which can screw with Flexbox
  • Stretching images is hard but possible by specifying a max, min width and using "flex: auto;"

JavaScript

  • This section took much longer than expected
  • I thought, knowing more "complex" languages such as C and Assembly, JavaScript would be a walk in the park, but boy is it hard to debug
  • JS is dynamically typed, meaning a variable can assume any data type at any point
  • "null" means empty or unknown while "undefined" means unassigned
  • Maps and JS objects are similar, but JS objects can have nested pairs
    • JS objects act similarly to JSON objects
  • All variables are global by default
    • Storing variables and methods inside of classes helps clean up the global namespace
  • Always sketch your user interfaces beforehand (learned this from a previous project, but thought it was worth reinforcing)
  • I have never had a reason to use one browser over another until I realized how robust Chrome's dev tools are
  • Comments tell us why code works, not how
  • When linking a JS script in the head element, you must use the defer keyword to correctly load elements from the DOM
  • Programming a calculator is harder than I thought...
