# assign

The `assign` method adds a table of attributes (name/value pairs) to the object.

## Syntax

    assign (attributes)

## Arguments

Argument | Description
--- | ---
`attributes` | (lua_json_object_type) The table of attributes to add. The keys in the table must be strings which specify the names of the attributes to add. Each value can be a Boolean, float, integer, string, LuaJsonArray, LuaJsonObject, LuaJsonValue, or nil. TIP: In Lua, keys in a table cannot be assigned the value of `nil`. If you want to have a null value (`nil` in Lua), you can do the following: `myJsonObject:assign( { key=LuaJsonValue:new(nil) } )`.

## Example

    local myJsonObject = LuaJsonObject:new()
    myJsonObject:assign( {
            attr1=LuaJsonObject:new( { n=42 } ),
            attr2=LuaJsonArray:new( 1, 2, "three" ),
            attr3=true
        } )
    print(myJsonObject:string())
    -- {"attr1":{"n":42},"attr2":[1,2,"three"],"attr3":true}
