hi guys, I’m currently working on The Odin Project, and one of the exercises asked me to create a function capitalize(). Here is the code: function capitalize(str) { return str.toUpperCase(); } When i tried executing the function on browser console, for example capitalize(hello) this error come…

You haven’t included quote marks around hello, so you’re trying to capitalise a non-existent variable, not a string.

[image] andreywjaya: capitalize(hello) Hi there! Hello must be a string, not variable here

hi, thank you so much! so without the quote marks “”, it didn’t recognize the parameter as a string ?

thank you for answering! just to be clear, without the quote, it doesn’t get recognized as a string ? so what is the type ?

That’s right. Without quotation marks your hello is treated as a variable
