VUEJS - How to Convert Date from API Response - vue.js

Question

I'm doing my project with API and the default birthdate from the response is YYYY-MM-DD but I wanna format and show the birthdate in my modal dialog in this format DD-MM-YYYY,
here's the code
axios
.post("test/test).
.then((response) => {
if (response.data.patients.length === 0) {
this.showAlert(this.$t("tess"), "error");
} else {
this.dataLoad = response.data.patients[0].patient;
console.log(this.dataLoad);
}
})
I save the response in dataLoad and wanna show the format DD-MM-YYYY in modal dialog
<v-row>
<v-col cols="4">Birthdate</v-col>
<v-col cols="1">:</v-col>
<v-col cols="7">{{
this.dataLoad && this.dataLoad.birthdate
}}</v-col>
</v-row>

Answer 1

Call the following function.
function formatDate(dateStr)
{
var parts = dateStr.split("-");
return parts[2]+ "-" + parts[1]+ "-" + parts[0];
}
Alternatively, you can use it as follows.
<v-row>
<v-col cols="4">Birthdate</v-col>
<v-col cols="1">:</v-col>
<v-col cols="7">{{
this.dataLoad && this.dataLoad.birthdate.split("-").reverse().join("-")
}}</v-col>
</v-row>

Answer 2

you can first of all prepare the birth Date like the format you want after that you can load it to your component:
new Vue({
el: '#vueRoot',
data: {birthDate: '1963-11-22'},
computed:{
birthDateDdmm(){
return new Date(this.birthDate + 'T00:00:00Z')
.toLocaleDateString('en-GB',{timeZone:'UTC'})
},
birthDateAuto(){
return new Date(this.birthDate + 'T00:00:00Z')
.toLocaleDateString([],{timeZone:'UTC'})
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id='vueRoot'>
<h1>input => {{birthDate}}</h1>
<h1>dd-MM-yy => {{birthDateDdmm}}</h1>
<h1>respect user prefs => {{birthDateAuto}}</h1>
</div>
