Let’s say we want to trigger an action when the user hits enter on their keyboard. We could do something like this, capturing the keydown<\/code> event and then decide what to do based on the entered key:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

While the above works, it’s pretty verbose. Instead, we can make our binding more specific by doing the following:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Now, that’s a lot more specific and less verbose. The same goes for class bindings. Here’s a lengthy example:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n

Since all we want to do is toggle the green class on or off based on a boolean expression, the following syntax is shorter and better:<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

<\/p>\n\n\n\n
