The result 20 will appear below your expression (unless your expression takes too much time to evaluate). The Console is a perfect place for these kinds of experiments. Sometimes, you just want a code playground where you can test some code, or try out new JavaScript features you're not familiar with. # Run arbitrary JavaScript that's not related to the page So "Hello, Console!" must be the result of evaluating document.getElementById('hello').textContent = 'Hello, Console!'. After evaluating your code, a REPL prints the result of the expression. Recall the 4 steps of REPL: read, evaluate, print, loop. How the Console looks after evaluating the expression above.īelow the code that you evaluated you see "Hello, Console!". Notice how the text inside the button changes.įigure 3.

See Get Started With Debugging JavaScript to learn how to pause JavaScript code and step through it one line at a time.
