⭐️ 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?
