S2JS - Asking, Saying and Manipulating Text : Getting the length of a string

Javascript strings are really powerful and have lots of built-in capabilities (called methods and properties).

The code in the sample below shows how you get the length of a string, using the length property.

It works the same as this Scratch block:

Try putting spaces at the beginning or end of the string (inside the quotes). Do they count in the length?

<HTML> <body> <canvas id=myCanvas height=200 width=200 style="background-color: khaki"> </canvas> <script> var ctx = myCanvas.getContext("2d"); var name = "Jonathan Swift"; var len = name.length; ctx.font="15px arial"; ctx.fillText("Name: " + name, 0, 20); ctx.fillText("Length:" + len, 0, 40); </script> </body> </html>
