checking if a string is empty.
Hey, i had a string that started off with the value
Is this a recommended way to check for an empty string and is that a recommended check to do if it's not checking for a boolean? thanks in advance.
"" and wanted to check if it was empty. I first tried if (xyz.length <= 0) {...} but found out that "" equates to nullif (xyz) which ended up working, this resource said that that tests for a value but i always thought that sort of if statement was for checking booleans (if (xyz) being "if xyz = true"). Is this a recommended way to check for an empty string and is that a recommended check to do if it's not checking for a boolean? thanks in advance.
