how to learn coding for the web with javascript

  • mozilla MDN guide: go through the modules (it's all in the sidebar) and the exercises
  • you can highlight and take notes with liner 
  • to do the exercises, 
    • you need to know: 
      • html, css and javascript -- you can look for for other modules on MDN
      • how relative file folder urls work - for working with img src
      • how to use the developer console function console.log()
    • usually the exercise folder contains: .js file, .css file, .html file and and image folder
    • you need these programs
      • to view output: 
        • a browser (i like google chrome), 
          • your html file opens in your browser
        • pressing f12 gives you the console, and the page source
        • you can you console.log() to test your code
        • you can view page source to see your html code
        • code editor for html, css, js
    • .html, .css, .js files: open in a code editor like VS. 
    • i also recommend the VS plugins 
      • ES6 - es6 refers to the latest version of javascript 
        • auto suggest/autocomplete javascript code
        • color codes code
        • mouseover reveals references' properties
      •  brackets - colorises brackets for nested code
    • your js, css, and html files are linked
      • so ctrl+s your js/css code and f5 your page to view changes
    • use console.log() to test code and trace your errors
javascript manipulates the actions in your html page/file. it can create, change, make it interactive
css styles your html page/file.

let me tell you the story of a green tea bitch and a hamsum with cheater potential.  i work closely with greentea in office. greentea has/had a long term boyfriend if more than 5 years (not sure if they still together, greentea always winces when i ask her about mr i-seriously-think-you-were-cuckolded nowadays). but she also crushes on the now ex-tech lead mr suave. suave probably left to avoid suspicion? i remember seeing her and her mr cuckolded boyfriend, she was cosying, rubbing her body against mr cuckold and leaning into him talking, on the mrt on our way back, from one of our get togethers. also knows he buys her hundreds dollar worth gifts on her birthday. (actually not very expensive i guess, she is into expensive gifts). ms prettii and mr suave ever played accidental touch ( hand brushing as they both reached for the mouse, then longing looks). she sent him a sticker of fingers touching on group chat before. anyway suave decided to teach us newbies coding in chinese (cos he s

this just came out. his recent songs are getting better, i'm impressed. metaphors and imagery on point. flying, running barefoot, looking back, blackened nails, tears in sleep, warm bright sunlight, dancing alone, flying free like a bird i relate to this because my life is to be honest, so-so in the friends department and non existent in the romance department.  i don't feel like really sad, or regret, or i need to change it. friends are busy and settled down,  some are less able to provide a listening ear (maybe to them it is childish, immature, or being listened to means you have have to reciprocate so maybe not, they have theirs at home already, they are stressed and have no more bandwidth for anything else).  that is the reality of being an adult. maybe the occasional sympathy and warmth from a colleague or friend or stranger. but that doesn't do it for me. i don't need the superficial. and i feel it is so easy to have values not align one day, or per
