this.setstate is not a function

Make sure you use arrow functions to correctly bind 'this'

 handlePageChange = (page) => {
        this.setState({ currentPage: page });
    }

This will give you 'this.setstate is not a function'

 handlePageChange(page){
        this.setState({ currentPage: page });
    }
