Could someone help me understand why a IIFE is used in The destructuring assignment to assign variables from arrays lesson? I finished the lesson and I’ve read through some of the links explaining IIFEs, but the purpose/benefit of using it in this application is not really clicking. TIA
That was my confusion.
I agree, it seems like they buried the actual problem in unnecessary layers in the code.
Am I missing some lesson they’re trying to impart? Or functionality that is possible by doing it the way the code stub sets it up?
Just don’t use ‘const’
[a, b] = [b, a];
