Understand String Immutability SOS

Tell us what’s happening:

Why is the code still marked wrong even though it was accepted? I do not understand the errors or if this was just a bug?

Your code so far

// Setup
var myStr = "Jello World";

// Only change code below this line

myStr ="Hello World";

Link to the challenge:

hello camper, you should remove this line “myStr[0];” and re-run the code. It should work perfectly.

Just throwing myStr[0]; on a random line is invalid JS, it does nothing, that’s why you’re getting an error.
