 ## FocusScope
 
-A focus scope declares that the last child element with `focus: true` receives the focus if the focus scope receives the focus. So it’s forward the focus to the last focus requesting child element. We will create a 2nd version of our TLineEdit component called TLineEditV2 using the focus scope as the root element.
