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
Not really sure, because if you remove the IIFE and just write the code to swap the variable values using destructuring assignment, it still passes the tests.
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];
