Update - Observables

[AbdellaToronto]

Observables

• Split the paragraph in 2

Using Observables

• Some corrections needed to the sample code (init() should be ngOnInit())
• Description needs to be updated to match the sample code (ie. nothing is happening in the constructor())
• Split this page into 2 (or add a header to split the ideas: subscribing to Observable & the use of subscribe vs. forEach)

Error handling

• Should have a small explanation of .complete()

Disposing Subscriptions and Releasing Resources

• Paragraph about onUnsubscribe: is this valid?
• Mention unsubscribing when a component is destroyed

Observables vs Promises

• First bullet point: replace “example above” with “previous example”

Using Observables From other Sources

• Change Http to HttpClient

Observables Array Operations

• Doesn’t explain what flatMap does
• RxJS API link could be updated to https://rxjs.dev/api

Cold vs Hot Observables

• Link the Hot Observable example
• I don’t think the .connect() method exists anymore (need new Cold to Hot example?)

Summary

• Revisit link list
• Add a description for the list of links (there is no context)
