Let’s be honest—most of us have been using Windows since we were kids. It’s the backbone of the corporate world and feels like the default choice for every computer user. For years, I thought it was the only real option. But what if I told you there isn't just an "alternative" out there, but a genuine upgrade? When people talk about switching to Linux , it can feel overwhelming because there are so many versions. However, I want to talk specifically about Ubuntu .
Now we have a useful operator in salesforce to avoid the null exceptions. Use the safe navigation operator (?.) to replace null checks. it's very useful to reduce lines of code and increase test class performance.
Before Safe Operator
String profileUrl = null; if (user.getProfileUrl() != null) { profileUrl = user.getProfileUrl().toExternalForm(); }
After Safe Operator
String profileUrl = user.getProfileUrl()?.toExternalForm();
instead of 4 lines Now we can make one line for this. Code looks more readble.
