More excersices about JS would help. Im working on it.
Typeof, and logic in general.
Boolean operators, Im still working on full understandment.
Doing excersices and videos online to catch up.

you mean you want us to provide more exercises or that you need to do more yourself? :)

you mean II and && ? https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Logical_OR https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Logical_AND

Yes, excercises on my own, the only way I think we can get to know the logic with JS is by repetition.
Im still catching up with Loops functions since I missed them in the 2 weeks I had Covid, Im learning on my own.
Functions practice in HTML (onclick)
loops in conjunction with other functions
Enrolled in a Scrimba paid course to catch up with functions, loops, arrays, objects and DOM, hopefully that helps me out to gain the time I missed due to Covid.

@TheRick88 is there a specific exercise you had trouble understanding and solving? you can also post it on Discord, so we can help

Scrimba is nice, but there are also plenty of free material and class recordings of HYF that you can find in the suggested study materials

Hey Daniel! Yeah, loops in general but just because I usually tend to try to understand every aspect of things so it takes me some time, but Im getting there, I know about the material and videos from HYF, but sometimes Im very visual learning so, yeah, Im using all the help I can get right now :)
I dont have an specific topic anymore, just practice to fully understand every topic so far.
Modifying arrays.
Syntax for util functions, but I guess just takes some practice.
Practice on my own.
Please, next sunday, even if no one has a question, please before the class start, do tha most difficult excercise from the homework and go step by step explaining. Sometime people are just ashamed to say they didnt understand.
Thank you!
Syntax for util functions, but I guess just takes some practice.
each imported, or util function works according to the author.. and in terms of syntax the same way as any other function..that we call and can pass parameters to.. is there anything specific regarding this that we can try to explain better? or is it the importing/exporting aspect? that will be covered in more detail later on..
Sometime people are just ashamed to say they didnt understand.
we can try to do that, although there is always a lot of material to be covered, and Sundays in general are meant to practice new things..if there are questions about past topics, it is recommended to ask coaches during the week.. that said, we can try to do as you say, especially that we will be online, so less time will be spent on socializing :D
I would like on Sunday to discuss the last refactoring excercise, I had some problems to understand the homework, also problems running test, would be ok to go over again with how to run the tests and we can use this excercise as example.
functions and syntax
refactoring, testing and debugging
Same as last week, please take some time to explain step by step the last excersice, but this week, please try to make it a bit slower and more explicatory, last week Jonathan did a good job and we appreciate it, but it was super fast and assuming he was explaining it to co-workers that already manage JS. We need a bit more of explaining.
Thank you again to all of you who take the time to teach us.

since we are covering new material on Sundays, these kind of questions would be great to ask the coaches during the week. that is one of the reasons why we have Discord. so please feel free to use the need-help or the code-review channels and ask. the coaches will reply whenever they have time and might even organise an extra zoom session.
Learning Objectives
Priorities: 🥚, 🐣, 🐥, 🐔 (click to learn more)
There is a lot to learn in this repository. If you can't master all the material at once, that's expected! Anything you don't master now will always be waiting for you to review when you need it. These 4 emoji's will help you prioritize your study time and to measure your progress: - 🥚: Understanding this material is required, it covers the base skills you'll need to move on. You do not need to finish all of them but should feel comfortable that you could with enough time. - 🐣: You have started all of these exercises and feel you could complete them all if you just had more time. It may not be easy for you but with effort you can make it through. - 🐥: You have studied the examples and started some exercises if you had time. You should have a big-picture understanding of these concepts/skills, but may not be confident completing the exercises. - 🐔: These concepts or skills are not necessary but are related to this module. If you are finished with 🥚, 🐣 and 🐥 you can use the 🐔 exercises to push yourself without getting distracted from the module's main objectives. ---
0. Asserting
let
vs.const
: You can explain the differences betweenlet
andconst
including: uninitialized declarations and reassignment. You can determine when a variable can be assigned withconst
in a program.===
and!==
operators compare strings, and can predict the result of any string comparison.console.log
: You can useconsole.log
to create program traces in the console, and to print other helpful info for developers.console.assert
: You can use theconsole.assert
for assertion testing, and can write a helpful message assertion message.1. Primitives and Operators
typeof
: You can predict thetypeof
operator's output for values from any of the 5 main primitive types.Boolean()
,String()
andNumber()
to convert between primitive types.&&
,||
,!
and? :
.&&
and||
.+
,!
and>
.2. Control Flow
if
/else
statements.while
loops.for-of
Strings: You can predict and trace simple programs that iterate through the characters of a string usingfor-of
.for
loops works by refactoring simplefor
loops intowhile
loops.break
.continue
.3. Functions
5. Unit Testing
describe
/it
/expect.toEqual
functions are defined by a testing library and made available as global variables in a testing environment. They are not part of JavaScript!file.__.js
. Sub-extensions are a convention for developers and development tools. They do not change how JavaScript inside the file works.6. ES Modules
?deps
lens to visualize the dependencies in a folder.'use strict'
!export const _ = () => {};
import { _ } from './path/to/file.js';
6. Using Functions
7. Arrays
const arr = ['items'];
.at()
and a positive or negative index.arr[4] = 'hello'
.Array.isArray(something)
const shallowCopy = [...arr];
8. Functional Array Methods
[].every
[].some
[].map
[].filter
[].find
[].reduce
9. Objects
const obj = { a: 1, b: 2 };
.
