Support typescript

[tientkc]

I'm using Libs in my project but I got a issue when I convert this project to using typescrpit:
`
TypeError: children is not a function
Diff/index.js:94
91 |
92 | return (
93 | <Provider value={{...remainings, monotonous}}>

94 | <table
95 | ^ ref={root}
96 | className={classNames('diff', diff-${viewType}, className)}
97 | onMouseDown={onTableMouseDown}
`
So you can update for project using typescript?
