I'm facing a puzzling issue that I can't seem to figure out. I'm attempting to verify if a variable is null in my React Native application, but the results are not as expected. Here is the console.log snippet illustrating my problem:
console.log(
this.props.until,
this.props.until != null,
this.props.until !== null,
!this.props.until,
!!this.props.until);
Here's what it outputs:
[null, true, true, false, true]
How is it possible for the variable to be null, yet not equal to null when compared? It has left me questioning my understanding of TypeScript.
I appreciate any insight or help you can provide on this matter. Thank you!
