Here is the code I am working with:
const executeGenerator = <T, TResult>(generatorFunction: Generator<unknown, T, TResult>) => {
const gen = generatorFunction();
};
However, I encountered this error message:
This expression is not callable.
Type 'Generator<unknown, T, TResult>' has no call signatures.
Can someone guide me on how to properly type a generator in TypeScript?
A generator function is a type of function that is designed to return a generator object when called. In this particular instance, the function runWithCancel is anticipating a generator object as input, rather than a generator function.
To address this issue, consider implementing the following code:
export const runWithCancel = <R, TNext>(fn: () => Generator<unknown, R, TNext>) => {
const gen = fn();
};
In the world of programming, a Generator emerges from a GeneratorFunction. Assuming that fn represents a function, it is safe to assume that the type of the function will be classified as GeneratorFunction, while the result stored in gen will fall under the category of Generator:
export const executeWithCancellation = <R, TNext>(fn: GeneratorFunction) => {
const gen = fn() as Generator<unknown, R, TNext>;
};
