vue Error parsing JavaScript expression: Unexpected digit after hash token

This error usually occurs when you are trying to use a hash symbol (#) in a JavaScript expression in a Vue template. The hash symbol is used in Vue templates to indicate an anchor link, but it is not a valid character in a JavaScript expression.

To fix this error, you should either escape the hash symbol using a backslash (\#), or use a different character that is not reserved in JavaScript expressions. For example, you can use the dollar symbol ($) or the at symbol (@) instead.

Here is an example of how to escape the hash symbol:

<template>
  <div>
    {{ 'Some text with a \# hash symbol' }}
  </div>
</template>

And here is an example of using the dollar symbol instead:

<template>
  <div>
    {{ 'Some text with a $ dollar symbol' }}
  </div>
</template>

By using a different character or escaping the hash symbol, you can avoid the "Error parsing JavaScript expression: Unexpected digit after hash token" error in Vue.
