}
```

```js {wrapper=false, lineNos=false}
function add(a, b) {
  return a + b
}
```

## lineNos=false

```js {lineNos=false}
function add(a, b) {
  return a + b
}
```

## lineNumbersInTable=false

> [!WARNING]
> Not recommended!

```js {lineNumbersInTable=false}
function add(a, b) {
  return a + b
}

## Highlighting

Highlighting in code fences is enabled by default.

```js {linenostart=287,hl_lines=[2,"8-10"]}
/**
 * check if a string is a JS object string
 * @example isObjectLiteral("{a:1,b:2}") // true
 * @param {string} str string to check
 * @returns {boolean} whether the string is a JS object string
 */
function isObjectLiteral(str) {
  if (typeof str !== 'string') {
    return false
  }
  str = str.replace(/\s+/g, ' ').trim().replace(/;$/, '')
  if (str.startsWith('{') && str.endsWith('}')) {
    return true
  }
  return false
}
```

Highlighting in shortcode highlight.

{{< highlight javascript "hl_lines=2 8-10,linenostart=287" >}}
/**
 * check if a string is a JS object string
 * @example isObjectLiteral("{a:1,b:2}") // true
 * @param {string} str string to check
 * @returns {boolean} whether the string is a JS object string
 */
function isObjectLiteral(str) {
  if (typeof str !== 'string') {
    return false
  }
  str = str.replace(/\s+/g, ' ').trim().replace(/;$/, '')
  if (str.startsWith('{') && str.endsWith('}')) {
    return true
  }
  return false
}
