const not working but let is (ARRAYS)

I've noticed the push and unshift was not adding it and showing in the console. I changed it to LET and it showed all 8.

let instruments = ['piano', 'drums', 'trumpet']; instruments.push( 'guitar', 'violin', 'triangle' ); instruments.unshift( 'cowbell', 'tuba');

is there something I did wrong? thanks in advance!

Hi Jesse,

Is this question in response to a specific video on here?, is so please can you provide the link and I will take a further look.

I tried the above code you provided and it worked fine in Chrome Dev Tools console as you say, so perhaps if you could provide the example that did not work, and I could look at that also to try and help.

let instruments = ['piano', 'drums', 'trumpet'];
instruments.push( 'guitar', 'violin', 'triangle' );
instruments.unshift( 'cowbell', 'tuba');

I also tried it using a const and this worked:

const instruments = ['piano', 'drums', 'trumpet'];
instruments.push( 'guitar', 'violin', 'triangle' );
instruments.unshift( 'cowbell', 'tuba');

Oh yes, not sure why it didn't tag the course. It was "adding to arrays". I tested both const and let and I have came to the conclusion that most likely I spelled "const" wrong and it wasn't reading it. Thanks for the info!

Ahhhh no worries, yes this is usually the cause of most errors when coding, I still do this a lot :D
