Fun facts app - I'm a total newbie and struggling to understand why my code isnt compiling

It appears to be the same as the tutor's but i'm getting the following alerts: 'variable xx was never mutated - consider changing'

Hey Becky Hayes,

Try changing those to var declarations to lets if they are never mutated. Next, you should do a product clean. Finally, do you mean to have that breakpoint on line 28? Drag the blue arrow on the line number off of it to remove it.

HI Becky,

Your code is compiling because a var takes more memory in the app because the app has to check if it changed all the time. But a yellow error just means you could do something better, not that something is wrong. So your code should run fine, but if you change the var to let, the errors should disappear.

Hope this helped out,

Greets, Jari

There is no problem with this issues, it is just some kinf of advising.My code has the same thing but it still compiles, don't worry about that
