Run function within Date in Vue.Js

Question

In a Vue.Js component I use this Script template as in the example. On a getter, I inserted a Return of what is received

const GetSegmento = () => (param) => {
  return (() => {
    return param
  })(param)
}

"He will be evolved as I can do what I seek here"

In my component I try to receive the Object or Value that my getter returns in data > segmento where I intend to use once for something else, what I’d like to know is, how do I get the executed return, or just the result in the case when using the Getter GetSegmento in part Data?

In case I put the this.GetSegmento(this.$route) within the Console.log is working perfectly, but would like to use within the Data if that is possible, of course, I do not know if it is possible or how to do.

export default {
  data: () => ({
    segmento: s => this.GetSegmento(this.$route)
  }),

  onIdle () {
    console.log(this.segmento)
  }
}

That’s what comes back when I use the form above

ƒ segmento(s) {
  return _this.GetSegmento(_this.$route);
}

The real goal is also to know if it is possible to use it in a Constant in the following example.

const segmento = s => this.GetSegmento(this.$route)

export default {
    computed: {
      ...mapGetters('Modules', [ 'Segmento1', 'Segmento2' ])
  },

  onIdle () {
    console.log(this[segmento])
  }
}

Explanation with Files

The file I’m referring to is a file of the kind .vue, one template in the following format

<template>
  <div>{{ segmento }}</div>
</template>

<script>
  import { mapGetters } from 'vuex'

  export default {
    data: () => ({
      segmento: ''
    }),

    computed: {
      ...mapGetters('GetUm', [ 'SegmentoUm' ]),
      ...mapGetters('GetDois', [ 'SegmentoDois' ])
    },

    mounted () {
      console.log(this.SegmentoUm(this.$route)) // funciona muito bem
      console.log(this.SegmentoDois(this.$route)) // funciona muito bem
    },

    methods: {
      getSegmento () {
        this.segmento = this.SegmentoUm(this.$route.meta.segmento) // funciona também
        this.segmento = this.SegmentoDois(this.$route.meta.segmento) // funciona também
      }
    }
  }

The only thing I want is to know if it is possible and how to carry out the execution and return of the result of SegmentoUm and or SegmentoDois within the data: segmento or within a const outside the export default as in the example below:

<template>
  <div>{{ segmento }}</div>
</template>

<script>
  import { mapGetters } from 'vuex'

  const segmento = this.SegmentoUm // ou aqui

  export default {
    data: () => ({
      segmento: this.SegmentoUm // ou aqui
    }),

    computed: {
      ...mapGetters('GetUm', [ 'SegmentoUm' ]),
      ...mapGetters('GetDois', [ 'SegmentoDois' ])
    },

    mounted () {
      console.log(this.SegmentoUm(this.segmento)) // então vejo aqui
    },

    methods: {
      getSegmento () {
        this.segmento = this.SegmentoUm(segmento) // ou aqui
      }
    }
  }
