it is only a alias of query(obj, keys).value

const obj = { a: { b: [1, 2] } }
query(obj, 'a.b[0]') // => 1

the string you wanna parse

if it's true, this funciton will create object or array when necessary

const obj = { a: { b: [1, 2] } }
query(obj, 'a.b[0]') // => { target: [1, 2], key: 0, value: 1 }

or with createTarget param

const obj = { }
query(obj, 'a.b[0]', true) => { target: [], key: 0, value: undefined }

const obj = { a: { b: [1, 2] } }
query(obj, 'a.b[0]', 3)
obj.a.b[0] === 3 // => true

the key arr you wanna stringify
