Can someone explain why the value of result in the following code is false?
const o = { name: "Brendan" }; const s = JSON.parse(JSON.stringify(o)); const result = s === o; I thought the value of result would be true since parse recreates the object after stringify converts o to JSON text. Thanks

It does, it recreates an object which looks the same, but is not the same object.
If you compare them by attributes, though, the comparison will be true.
Try:
s.name === o.name

Thank you for your response - I really appreciate it. I guess then the point of confusion for me is the meaning of === in this context - I realize that the recreation is a new object with identitical property/value pairs, but my understanding was that the === comparison operator was checking to see if two variables/arrays/data type were of equal value and data type, not that they are identical variables or containers - my apologies, still a beginner and trying to wrap my head around this.
