Get or set a value in an object/array using a dot-delimited string or array of keys.
Returns the value in obj corresponding to path. Returns undefined if path does not exist.
obj — An object or array.path — A dot-delimited string of keys, or an array of keys.var obj = {
foo: {
bar: ['Hello', 'World'],
baz: 'Goodbye'
}
};
jaunt.get(obj, 'foo.bar'); //=> ['Hello', 'World']
jaunt.get(obj, 'foo.baz'); //=> 'Goodbye'
jaunt.get(obj, 'foo.bar.0'); //=> 'Hello'
jaunt.get(obj, 'foo.baz.0'); //=> 'Goodbye'
jaunt.get(obj, ['foo', 'bar', 0]); //=> 'World'
jaunt.get(obj, ['foo', 'baz', 0]); //=> 'Goodbye'
jaunt.get(obj, 'invalid'); //=> undefined
There can be a trailing “0” in path if it corresponds to a leaf node. So, in the example above, the paths foo.baz and foo.baz.0 are equivalent.
Sets the element corresponding to path in the obj to the specified val. Any “intermediate” elements in the path will be created if they do not exist. Returns the modified obj.
