This could be achieved by calling reduce on your array of values (ie data), to obtain the required hash map (where ID is the key and value is the corresponding LABEL):
const data = [
{ID: 0, LABEL: 'turbo'},
{ID: 1, LABEL: 'classic'},
{ID: 7, LABEL: 'unknown'}
];
const hashMap = data.reduce((result, item) => {
return { ...result, [ item.ID ] : item.LABEL };
}, {});
const hashMapJson = JSON.stringify(hashMap);
console.log('hashMap', hashMap);
console.log('hashMapJson', hashMapJson);
/*
More concise syntax:
console.log(data.reduce((result, { ID, LABEL }) => ({ ...result, [ ID ] : LABEL }), {}))
*/
