    How to recover a dropped stash in Git?

1. Find the stash commits:
git log --graph --oneline --decorate ( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )
This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

    What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Element

Box metrics


elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
elem.getClientRects(), elem.getBoundingClientRect()

                replace AngularJS expressions with Angular expressions
              
          
    *ngFor

Заменяет старый синтаксис ng-repeat="item in obj.items track by $index" или ng-repeat="item in items track by $index" на новый *ngFor="let item of obj.items; trackBy: trackById;" или *ngFor="let item of items; trackBy: trackById;"
Выражение:
ng-repeat="([a-zA-Z]*)\s+(in)\s+([a-zA-Z\.{1}().]*)\s+track by \$index"

                How to deal with android emulation on Windows
              
          
    Решил проблему незапускающегося проекта следующим образом:

установил всё строго по дваноому мануалу: https://evothings.com/doc/build/cordova-install-windows.html


В пункте Install the Android Tools ограничился установкой Android Studio


Далее установил Cordova, инициализировал проект (по оф. сайту)


При запуске cordova emulate android вылезала ошибка: Cannot read property 'replace' of undefined. Решил это как описано здесь: https://stackoverflow.com/questions/44687476/cordova-android-emulator-cannot-read-property-replace-of-undefined


В Android Studio в settings нужно
