Two mutables don’t make a right
Two mutables don’t make a right
“Don’t put mutable collections inside mutable state holders.” - Zach Klippenstein
The key idea here is that if you have a mutable collection in a mutable state holder, update the mutable collection, then an update won’t be passed to whatever is listening to the state holder’s changes.
Zach goes into excellent detail in his post about why this happens.
I highly recommend his whole series that this article is from.

⭐️ Answer to Last Week's Question
Last week we asked:
Kotlin supports multiple types of object equality. What are they? What are the differences?
There are 2 types of equality in Kotlin
  • Referential Equality
  • Structural Equality
Referential Equality
This type of equality is checked with the === operation and is negated by !==. Consider a === b. This will true if and only if a and b point to the SAME object.
⚠️ Note for primitive values like Int, === is the same as ==.
Structural Equality
This type of equality is checked with the == or .equals() operation and has a negated counter part of !=.
Consider a == b. This is evaluate as:
a?.equals(b) ?: (b === null)
So if a is not null, then .equals() is called to compare a and b. If a is null, then b === null evaluates because of the elvis operator (?:). This referential equality check determines if b is truly null and returns true if it is, and false if not.

💭 Quote of the Week
Hopefully you had a nice break from work over the weekend (a long weekend for some of you)! We are now quickly approaching the end of the year. A time for reflection and goal settings. I want to start off the season with this quote:
“Whether you think you can or think you can’t, either way you are right.” - Henry Ford
Keep this in mind as you begin setting goals for next year. Having confidence in yourself is a huge first step! You can do this, it just takes time.
At this time next year, what will you be thankful you spent time on during the next 12 months?
