Hope this helps Aggregate query returns an error. , Before
code :
Model.aggregate({
  $group: {
    _id: "$id",
    count: { $sum: "$like.count" }
  }
})
Model.aggregate([{
  $group: {
    _id: "$id",
    count: { $sum: "$like.count" }
  }
}])

How to ensure that this qi parser disallows spaces between the dot operators?

Hope this helps qi::lexeme[] accets only no-skipper rules.
You can declare identifier and simple_var as:
code :
qi::rule<Iterator, std::string()> identifier,simple_var;
variable %= lexeme[simple_var % '.'];

Typescript throwing errors for spread operators

I think the issue was by ths following , The errors imply that JSX syntax wasn't recognized by the compiler. In order for it to be recognized, the file should have .tsx extension, while it currently has .ts extension.
jsx compiler option should also be enabled and set to react.

Calling function using spread operators

like below fixes the issue Is there a way I could shorten this using spread operators so I am not having to call the createtab function over and over. Especially in cases where I have a much bigger and deeper navigation bar? , You can send all the pages in array to createTab
code :
   function NavTabs(props) {
      return (
        <ul className="nav nav-tabs">
             {createTab(["Home", "About","Blog","Contact"]  , props)}
      </ul>
      );
  };
  function createTab(pages, props) {
       return pages.map((page, index) => (
               <li key={"Key-"+index} className="nav-item">
                   <a href={"#" + page} onClick={() => props.handlePageChange(page)} className={"nav-link" + (props.currentPage === page? " active" : "")}>
                      {page}
                   </a>
              </li>))
          };

Assign Array of types to spread operators

wish of those help You don't need to spread the tuple type, the spread is needed just on the parameter:
code :
type Arr = [true, false, "string"]

function func(...param: Arr) { }
func(true, false, "string")
func(true, false, "stringg") // err

type Promisify<T> = { 
    [P in keyof T]: Promise<T[P]>
}


function func2(...param: Promisify<Arr>) { }
// Same as 
// func2(param_0: Promise<true>, param_1: Promise<false>, param_2: Promise<"string">): void


react-redux useSelector hook disallows passing props directly to the selector

wish help you to fix your issue I've just started playing with the new useSelector hook provided in react-redux. , This is good practice to use props in selectors.
code :
import React from 'react'
import { useSelector } from 'react-redux'

export const TodoListItem = props => {
  const todo = useSelector(state => state.todos[props.id])
  return <div>{todo.text}</div>
}
