useEffect( effect: async () => {
await companydata()
}, deps: [])
have you tried adding async and await inside useEffect hook

Try to change your code like this:
import React, { useEffect, useState } from 'react';
import axios from 'axios';
function Companies() {
const [companies, setCompanies] = useState([]);
useEffect(() => {
companydata();
}, []);
const companydata = async () => {
const { data } = await axios.get('http://localhost:5000/api/v1/companies');
setCompanies(data);
};
return (
<div className='companies'>
{companies.map((comp) => (
<div key={comp.CompanyId}>
<h5>{comp.CompanyName}</h5>
</div>
))}
</div>
);
}
export default Companies;
