# String template

## Function
 String template is used to embed variables or expressions in strings, suitable for generating prompt text, HTML fragments, SQL fragments or log content.

## Syntax
```bt
name = 'BT'
text = `Hello ${name}`
```

## Usage recommendations
- Use backticks to wrap template strings.
-`+` can be used for simple splicing. Template strings are preferred when multiple variables are included.
- Parameter binding is still required when splicing SQL to avoid writing user input directly into SQL.
