///////////// I want to push the string array data to json object with label & value//////
// I experimented alot but giving some type error and all I am not getting
localIds.push({ label: 'abc', value: 'abc' });
localIdentifiers.map(i => localIds.push(...localIds:{value:i,label:i}[])); //ERROR
Half of your code does nothing useful
result.data.map((item: string) => item) will do nothingmap when not returning anything inside it is pointless. At very least use forEach instead. or even better....You should use map with concat:
interface LocalIds {
value: string;
label: string;
}
const localIds = [
{ value: 'test', label: 'test' },
{ value: 'test2', label: 'test2' },
];
localIds.push({ label: 'abc', value: 'abc' });
const finalLocalIds = localIds.concat( result.data.map((i: string) => ({value:i,label:i})) );
Try fixing last line as following
replace ; with , and remove [] at the end
localIdentifiers.map(i => localIds.push(...localIds, {value:i,label:i}));
also, you dont need ...localIds, since it will duplicate current array every time element is pushed to array
