object object output 的使用状态钩子

Question

Greetings iam in need of help so I am taking an online course of react and I followed sir Kalob step by step but while assigning keyword using usestate() it is printing [object object] instead of the actual keyword which I set using hook and so I tried to look for different solutions from useState("searching for") I changed it to useState({name:"searching for"}) and while assigning it to keyword i changed it from keyword={searchText} to keyword={searchText.name} but still, it's giving me the same output I am out of solutions any help would be appreciated. All necessary screenshots are attached. enter image description here

const SearchView =(keyword,searchResults)=>{
    const title =  `You are searching for ${keyword}`
    console.log(searchResults,"are the search results")
    return(
        <div>
            <Hero text ={title} />
        </div>

Answer 1

Pass the props that SearchView should have through the component prop while calling the component.

<Route 
  path='/search' 
  component={
    <SearchView keyword={searchText} searchResults={searchResults} />
  } 
/>

And your output is [object Object] because you're logging the props object, not the keyword string. Add the destructuring assignment of the props to actually get the props that are being passed.

const SearchView = ({ keyword, searchResults }) => {
  const title = `You are searching for ${keyword}`;

  return (
    <div>
      <Hero text ={title} />
    </div>
  );
}
