Chrome’s developer console tab is great for playing around to understand or troubleshoot a web application. The other day I wanted to enter more than just a simple one line expression in the console. In this case I wanted to define a whole function across several lines. I wasn’t sure if that was possible. Turns out it is.
To enter more than one line without the console evaluating the first line immediately, simply use
SHIFT + ENTER at the end of each line. Then when you’re done press
ENTER as usual to have the whole snippet evaluated.
