Usage of "=="

Hello everyone,

As I am making my way through these courses I am trying to make sense of how these practices would be used in a coding scenario. I am assuming this is not used to check something in the code itself as you could look at two values and see of the are equal to each other. Would this be something that would be useful in the following example?

user is setting up and account and needs to input a password twice.

would this compare the two values and return an error if the passwords don't match?

if you use it with a proper string comparison function then it will give an error, if the password doesn't match.

You had it right the first part. “==“ is a comparison operator. It checks if the value on both sides is equal. More info can be found in the Apple Documentation Just jump down to the comparison section and read that.
