Unweaving the intricate web of JSX child components

I've been doing some research online and I noticed that the create element function is being called with children as strings instead of objects. Thanks for any help!

Below is the code:

export function createElement(tag: string, props?: any, ...children: JSX.Element[]){
   let el = "<"+tag+">";

   if(props != undefined){
        for(let i of children){
            if(i == undefined)
                throw new Error("Expected class got undefined");
            else{

            }
        }
   }
   el+= "</"+tag+">"; 

   return el;   
}

Any suggestions on how I can ensure that children are not an array of strings?

Converting a JSX string "on the fly" into actual instances of JSX.Element is quite a complex task, often involving manipulating tsc to transpile your generated string into corresponding classes. Unfortunately, there hasn't been a widely accepted solution to this issue yet.

However, in many scenarios, parsing arbitrary JSX strings may not be necessary. This is especially true when you are working within a limited set of possible elements that can be instantiated in a similar manner. For instance, you could simplify the process using a switch statement like this:

let ComponentClass;

switch(tag)
{
    case "MyComponent":
        ComponentClass = MyComponent;
    break;

    case "MyOtherComponent":
        ComponentClass = MyOtherComponent;
    break;

    // Additional cases / default can be added here
}

return <ComponentClass {...props}>{children}</ComponentClass>;
