# existsByPath

The `existsByPath` method checks whether a specified path exists in the JSON object.

## Syntax

    existsByPath( path )

## Arguments

Argument | Description
--- | ---
`path` | (string) The path to check. Construct the path from array indexes and object attribute names, and use a slash (`/`) as the separator. If an object attribute name includes a slash, then escape the slash with a backslash, for example `"one\\/two"`. Notice that you must also escape a backslash with another backslash.

## Returns

(Boolean) Returns `true` if the path exists, `false` otherwise.

## Example

Consider the following JSON:

    {
      "product": "IDOL",
      "component": "CFS",
      "version": { "major": 11, "minor": 3 },
      "ports": [
        { "type": "ACI", "number": 7000 },
        { "type": "Service", "number": 17000 }
      ]
    }

If this JSON is represented by an object named `myJsonObject`, you could use the `existsByPath` method as follows:

    print (myJsonObject:existsByPath("ports/0/type"))
    -- true (LuaJsonArrays are zero-indexed)

    print (myJsonObject:existsByPath("ports/2/type") )
    -- false (LuaJsonArrays are zero-indexed, and there is no third value)

    print (myJsonObject:existsByPath("version/major"))
    -- true
