Ömer: Debugging, 4

[omerjava]

• 🥚 Stepping Through: You can:
  • [x] Pause a script in a step debugger (breakpoints and debugger statement)
  • [x] Arrange the debugger, collapse extra panels
  • [x] Step through a script written with Just Enough JS.
  • [x] At each point in execution you can make a prediction of the next line before executing
  • [x] Check your prediction using the scopes panel.
  • 🥚 Assertion Testing:
• [x] You are familiar with assertions
• [x] Can use console.assert to guide your study of a program.
• [x] 🥚 Linting: You can find and fix linting errors in JavaScript programs.
  • 🥚 Naming Variables: You can:
• [x] Analyze a program's variables using a structured comment
  • Rename the variables and give each variable two different names:
  • [x] Generic: A name that describes the variable's role in a general way. This includes deciding whether to use let or const.
  • [x] Specific: A name that fits the variable's role and contextualizes it in the program's domain.
  • [ ] 🥚 Program Life Cycle: You can explain the two phases of a program's life cycle.
  • [x] 🥚 Fixing Errors: You can use the structured comment to describe an error in your program, and can make several educated guesses at how to fix the error.
  • 🥚 Documenting Functions: You can:
• [x] Demonstrate your understanding of arguments, parameters
• [ ] Return values by writing a JSDoc comment.
  • 🐣 Explicit Coercion:
  • [x] You are aware of the rules for casting explicitly between types
  • [x] Can complete assertions to describe what value will result, they can have access to the internet and a console.
  • [x] 🐣 Implicit Coercion: You are aware that operators will implicitly cast operands to the same type before operating. They can look or experimentally discover the rules for an operator.
  • 🐣 Statements vs. Expressions: You can:
  • [x] Explain the difference between a statement and an expression
  • [x] Identify them in a program. This will be very helpful for understanding how the debugger steps, and for ...
  • [x] 🐣 Operator Precedence: You can refactor an expression with several operators into several statements assigning each step of the expression to a new variable according to the languages rules of operator precedence.111
  • [x] 🐣 Fixing Bugs: You can use the structured comment to describe and fix a bug in small programs.
  • 🐣 Reference vs. Value: You can:
  • [x] Explain how to swap references or values between variables
  • [x] Explain deep vs. strict equality
  • [ ] Compare two objects or arrays.
  • 🐣 Procedural Programming: You can:
  • [ ] Tell whether or not a JS program is Procedural
  • [ ] Explain how you made your decision.
  • [ ] 🐣 Side-Effects: Given a function that takes an array as an argument you can determine if the function has any side-effects, and can suggest a way to avoid the side-effect.
  • 🐣 Debugging Functions: You can:
  • [x] Read input/output assertion tests to understand a function's actual vs. expected behaviour
  • [x] Correct the function's behaviour.
  • [ ] 🐥 Sub-Goal Authoring: Given most of a small program with missing goal, you can write code to implement the missing behaviour.
  • [ ] 🐥 Hoisting: You can find hoisted functions and variables in the browser's debugger and explain how hoisting is related to program life-cycle.
  • [ ] 🐔 Refactoring Functions: You can refactor a designated chunk of a program into an empty function body and pass the given assertion tests.
  • [ ] 🐔 Reverse-Engineering: You can write a small program from scratch that matches the behavior of an example program.

 _

What went well?

• I learned 2 good websites last week in the class for code exercises thanks to @denrique-alvarez : Projecteuler and Codewars

What went less well?

 _

Lessons Learned

• I learned the use of 'debugger;' code in JS
• I learned console.assert() method in JS
• I learned some tips about how to decide using while or for loop
• I understand better the use of boolean variables but need more code exercise about it

Sunday Prep Work

• Reading the suggested study materials
• Doing exercises in JS tutor

[colevandersWands]

@omerjava , if you're already going into code challenges you might want to check out solution-write-ups, it's an exercise from the Behavior Strategy Implementation module

Ok. I will look at. Thank you!

[denrique-alvarez]

You are welcome! Trying to learn some more so we can discuss some problems together soon :)

What went well?

• I am solving code problems in code challenge websites, it contributes a lot to my theoretical knowledge. I feel I improved a lot myself in for, while loops and in use of arrays. I also practiced well some built-in array/string/number methods and some array iterators. I am very familiar now with methods such as split(), push(), String(), Number(), reverse(), includes(), join().

Great to hear that you are learning and exploring. 💯

[omerjava]

Thanks @gelilaa !

Week 12

Check-In

I Need Help With:

 _

What went well?

• I am now familiar with for..of loop and their difference from "for" loop
• I got used to creating an empty object variable and assigning "properties/keys : values" to them by using "for" loop. Very handy to find how many times numbers or letters repeat in a string. I can apply it in problems now.

What went less well?

• I can't work as much as I want now due to time constraint. But my fulltime job will end soon and I will able to focus on totally coding.

Lessons Learned

• Now, I am comfortable with using for..of loop.
• Better understand splice() and slice() methods, they are also very useful
• Learned to make an infinite loop with for..of loop. It is fun :)

@omerjava let us know if you need any extra one-to-one time with the coaches (from what we can see, you are doing very well even with the time constraint)
