chapter3 | Code examples for Chapter 3 of Ionic in Action

I am following along with this tutorial for installing Magento 2.3 on Ubuntu. I am able to get up to the point where I'm supposed to use composer to create a Magento 2 project using this command:

In the putty manual outlines how to use the program with command line parameters. I have this setup with a shortcut on my toolbar to automatically log me into my server.

I'm trying to follow along the lecture from spacy.io.

However, I ran into a strange problem.

Firstly, I share the link for the code from official spacy webpage.

https://course.spacy.io/en/chapter3

in the example code they provide,

i did a request to the API, then the response is as the following:

data1 = [{id: 1, code:1, title:title1}, {id:2, code:3, title:title2}, ...]

Now i would like to extract an array of the titles of the above response as below:

titles = [title1, title2, ....]

how can i do it by map?

And the second question:

Consider if the response would be as follow:

data2 = [{id: 1, code:1, title:title1, chapters:[{id:1, chapter: chapter1},{id:2, chapter: chapter2}, ...]}, {id:4, code:5, title:title3, chapters:[{id:4, chapter: chapter3}, ...]}, ...]

In this case how can i extract an array of the chapters as following:

chapters = [chapter1, chapter2, chapter3]

I tried to do them as below:

for the first question:

title = data1.map((item) => {item.title})

for the second one i did:

chapters = data2.chapters.map((item) => {item.chapter})

But it doesn't work. I think some where there are error in syntaxes.

Can any one help me how to manage these data? Thank you.

Does Jython have a ternary operator? I was unable to find it in the guide. edit: I am using weblogic's jython 2.2.1

I have a quite strange crash in my XCTest suite.
The test target is Application tests with Allow testing Host Application API checkbox enabled.
Build for active arch only is YES.

Now I have only ONE test in my test suite, and it still crashes.
Xcode says that the cause of crash is "Heap corruption". I've seen the possible reasons of heap corruption, it seems none applies in my case.

When testing with Address Sanitiser and Behaviour Sanitiser, I get smth like this:

The test looks like this:

I have a sidebar with anchor links that point to a specific content part when I click on them.

The problem appears when I'm scrolling the content, the link in the sidebar gets highlighted when the section title barely appears at the bottom.

How can I make the link change when the title of chapter content reaches the top of sidebar?

Here's what I tried so far but isn't working exactly as I want.

I have a sidebar with links that are changing when I'm scrolling a long content. The problem is that the change is happening too early when the chapter title is barely at the bottom of the page.

How can I write if(fromTop >= 100) differently, to get sticky when it reaches the row startContent?

Thanks for any suggestions!

I see git repos for tutorials with branches corresponding to each chapter of the tutorial. So in chapter one for example the tutorial is teaching how to create the home page, in chapter 2 how to connect it to the back end.

Chapter 1 has a chapter1 branch in the git repo that only has the main page

Chapter 2 has chapter2 branch that has the main page + the script that calls the API , and so on.

Now let's say that at one point (chapter 3) we want to change the colors and styles for the home page, and we want that reflected in all the branches for chapter1, chapter2 and 3.

Merging the changes to styles that was made in chapter 3 will also merge all the changes back to chapter1 not, so chapter1 and chapter3 branches will be identical. Which we don't want.

is there other way to do that other than manually copying and pasting the required changes?
