StaticDateRangePicker Error

[a-m-dev]

Hello

i was checking the library and i found this https://v4-0-0-alpha-5.material-ui-pickers.dev/demo/daterangepicker#static-mode

i was wondering why this is written in TypeScript?
if its in alpha version it needs to be used as simply as possible with pure react, right now i cant convert it to pure react and im keep getting this error in my console

Uncaught TypeError: Cannot read property 'keyboardDate' of undefinedblah blah blah

The above error occurred in the <RangePickerWithStateAndWrapper> component:
blah blah blah

Uncaught (in promise) TypeError: Cannot read property 'keyboardDate' of undefined
blah blah blah

please provide a gist of pure javascript for this 😭
and try to show it in pure javascript file not shitty type script 😭 to know how it works in react and then we check that in typescript!
