  • Do you have more context? Just an image, suspected error and code isn't gonna cut it. The code shown doesn't look likely to be the source of the error anyways. – kelsny Sep 11 '22 at 05:12

The React.js error "Expected an assignment or function call and instead saw an expression" occurs when we forget to return a value from a function. To solve the error, make sure to explicitly use a return statement or implicitly return using an arrow function.

Here is the screenshot of issue

  • return ; returnig this at the end of function call – SANIA ANJUM Sep 11 '22 at 05:31
  • this error is coming from the function which you are using just below "elements.push({ data: { source: 'one', target: 'two', label: 'Edge from Node1 to Node2' } },);" Not when you are pushing an element - so what ever you are returning from the function assign that to any variable/const - then use it. – Ankit Singh Sep 11 '22 at 05:41
  • (async () =>{ const repositoriesResponse = await octokit.request("GET /user/repos"); })(); // using async to fetch repositories of my github - using arrow function to return this – SANIA ANJUM Sep 11 '22 at 06:01
