users_hash[key] = value

Why not this method?

Hi,

Thanks, for this,

You may also want to mention that if there is a duplicate key in the new hash, it will overwrite the original hash.

So if I did this on the original hash:

users_hash.merge(”tom” => “changed_password”)

It would change the original hash , thus changing tom’s password to be ‘changed_password’.

Thanks for this example. Though it is simple, I found it useful.
