i have a list of countries with id i want to pull the country id of a specific country name 

 export const country_list_with_id = [
        {
            id: 1,
            code: "AF",
            name: "Afghanistan"
        },
        {
            id: 2,
            code: "AL",
            name: "Albania"
        },
        {
            id: 3,
            code: "DZ",
            name: "Algeria"
        },
        {
            id: 4,
            code: "DS",
            name: "American Samoa"
        },
    ...

if have country name like 

countryname = algeria

is there a function to help me easily retrieve its country id 

getcountryid(countryname){
return id 
}

I Found a solution 

   getcountryid(countryname){
   country_list_with_id.map(res=>{
    if(res.name === country name){
       return res.id
        }
       });
      }

I think you can do something like that:

country_list_with_id.find(country=> country.name.toLowerCase() === countryname)

You can create your own function like this, supposing you already saved your data in an Array of Objects :

myResponse = [];

function(country) = {
 var id=0;
 this.myResponse.forEach((res) => {
     if (res.countryname.toLowerCase() === country) {
      id = res.id;
     }
  }
}

Or using find instead :

var countryName = "algeria";
var found = this.myResponse.find((res) => {
  return countryName === res.countryName.toLowerCase();
});
