Chrome DevTools: Instant results for your JavaScript expressions

This feature gives you instant results for many side effect free JavaScript expressions. For example, you can type the following in the Console Panel:

`2 + 2 = ${2 + 2}`

And observe the result is:

"2 + 2 = 4"

Without having to hit enter.

Results are displayed as you type which makes this a powerful debugging tool.

This is a hidden experimental feature named Console below-prompt UI.
