In an attempt to dispel the idea that if you have to google stuff you’re not a proper engineer, this is a list of nearly everything I googled in a week at work, where I’m a software engineer with several years’ experience
I've long maintained that after 10-years coding I simply know the question to ask Google faster and can evaluate the answers better. I still look up the exact names of WordPress functions many times a week. I look up the order of the parameters and how exactly to get the value of a select box with jQuery.
I've looked all of these things up before, and I'll likely look them up again.
If you're just starting as a developer, looking stuff up on Google and in documentation is what developers do.
