Console logs are displayed, but it doesn't re-render.

CodePudding user response：

.sort array method mutates the state and you should avoid this. You cannot mutate anything in React, because it is not able to re-render. You should set the new state directly.

In your case you should create a new array, sort it, and set into your state:

function sortCompany () {
 const sortedUsers = [...users]

 sortedUsers.sort((x,y) => {
   if(x.company.name < y.company.name) {return -1}
   if(x.company.name > y.company.name) {return 1}
   return 0
 })

 setUsers(sortedUsers);
}
