Vue.js and Vuex - best practices for managing your state

Modifying state object

Example

If you have to extend an existing object with additional property, always prefer Vue.set() over Object.assign() (or spread operator).

Example below explains implications for different implementations.

private var observerContext = 0

class StackableWebView: WKWebView {
    
    // Keep track of height which will change when the view is loaded.
    var webViewHeight: CGFloat = 0.0

Reasons to create UIs in code rather than Storyboards:

Merge conflicts 

Easier to diff revisions and see changes in code

More flexibility to move UI elements on iPad vs iPhone,
portrait vs landscape

Easier theme support

// check version
node -v || node --version

// list locally installed versions of node
nvm ls

// list remove available versions of node
nvm ls-remote

// install specific version of node
