 7 !!omap [ ... ]              # array of key-value pairs
 8 !!pairs [ ... ]             # array or array pairs
 9 !!set { ... }               # array of objects with given keys and null values
10 !!str '...'                 # string
11 !!seq [ ... ]               # array
12 !!map { ... }               # object
13 
14 !!js/regexp /pattern/gim            # RegExp
15 !!js/undefined ''                   # Undefined
16 !!js/function 'function () {...}'   # Function

 

9.一些特殊的写法

Note, that you use arrays or objects as key in JS-YAML. JS do not allows objects or array as keys, and stringifies (by calling .toString method) them at the moment of adding them.（有空再翻译 囧）

1 ---
2 ? [ foo, bar ]
3 : - baz
4 ? { foo: bar }
5 : - baz
6   - baz

 

1 { "foo,bar": ["baz"], "[object Object]": ["baz", "baz"] }
