Moving on Up While Feeling Stupid

So I actually did go to bed and get up at a great hour, but I screwed off with the new Music update for a good hour. It cut into my coding time but I finally settled in around 1 PM, a full four hours after I woke up and one after I scheduled to code.

So I continued to tackle while loops. The idea of scope was covered. But writing my own for, do, and while loops I kept forgetting to declare a condition in a variable. Then I also forgot about global and local scope. So my loop looked something like this:

var count = 1;
for (var i = 0; i < 10; i++) {
 while(count < 3) {
  console.log("What the fuck am I even doing");
  count++
 }
}

I was so frustrated with the fact I felt like I was flying blind that I had a total give up console.log in the loop (pardon the expletive).

I didn\’t understand why this executed. So I turned to the Code Newbie Slack team and after a long while with me looking like an idjit, I came to realize the loop I wrote was awful. Awful because it didn\’t take into consideration the scope, local and global.

So the first line, my condition, is in global scope. This screws up everything inside the while loop. Once count increments from 1-3, it stays at 3 and doesn\’t reset because I didn\’t explicitly set the condition locally. Also, the forloop loops around 10 times and fails 9 because I\’ve declared countoutside the forloop. So for count which starts at 1 and increments by 1 to 3 until the loop fails, which it fails at 9 times, according to the for loop. The console.log prints out the string according to the count twice and then runs 9 more times and fails. It gets stuck at 3 and never resets…still thinking about why there.

Here is what the loop should look like, to include local scope:


for (var i = 0; i < 10; i++) { var count = 1; while(count < 3) { console.log("What the fuck am I even doing"); count++ } }

Feeling stupid much?
(Thinking about this while Rihanna sings \”Bitch better have my money\” on Beats1, Ha. Maybe I should turn it down…)

So next post will be about Arrays and Objects because yes, I am there finally!!! I have an idea for my languishing CodePen.io account. Arrays and objects change everything.
