Ways to display a variable prior to making an axios request

I have a get request that saves the result in a variable named name_student. How can I access this variable in other methods? Or how should I declare it?

Here is the code snippet:

getStudent(){
  axios.get('https://backunizoom.herokuapp.com/student/2')
        .then((result) => {
          console.log(result.data)
        this.name_student=result.data.name
        console.log(name_student)
        
    })
    console.log(name_student)
},

javascript vue.js

Using Shared Data Properties

In response to suggestions from @scar-2018 in the comments section, it is recommended to define name_student as a data prop so that it can be accessed by all component methods and hooks:

export default {
  data() {
    return {
      name_student: '',
    }
  },
  methods: {
    getStudent() {
      axios.get(/*...*).then((result) => {
        this.name_student = result.data.name

        this.updateStudentName()
      })
    },
    updateStudentName() {
      this.name_student += ' (student)'
    }
  }
}

Handling Asynchronous Data Access

If you are encountering issues with accessing data asynchronously and seeing undefined when logging name_student, it may be due to the asynchronous nature of the axios callback. Ensure that you are logging this.name_student after it has been modified by axios:

axios.get(/*...*/).then((result) => {
  this.name_student = result.data.name
  console.log(this.name_student) // => 'foo' ✅
})

console.log(this.name_student) // => undefined ❌ (not yet set)
