Error while rendering json data [Reactjs]

The data is in this form:


_getTags() {
return => {
var newItem = => <span className="tag" key={p.tag_id}>{}</span>);
return ({newItem);

So when I'm running this I'm getting:

error react.js:18893 Uncaught Error: Objects are not valid as a React child (found: object with keys {newItem}). If you meant to render a collection of children, use an array instead or wrap the object using createFragment(object) from the React add-ons.(…)

What am I missing?

Is there another way around?


there are two issues here.. one is that you are returning a nested list [[]] I think you probably wanted to return just a single list []. you are also returning {newItem} from your outer map function. That is not something React can render. React needs a react element or a list of react elements.

did you mean to do:

return => {
      return => <span className="tag" key={p.tag_id}>{}</span>);

or possibly

  .reduce((tags, view) => [...tags, =><span className="tag" key={p.tag_id}>{}</span>)], [])
