// Sometimes we use `as const` to have a more specific type,
|
|
// because TypeScript by default will widen the value type of an
|
|
// array literal. Consider the following example:
|
|
//
|
|
// const filter = [
|
|
// { term: { 'agent.name': 'nodejs' } },
|
|
// { range: { '@timestamp': { gte: 'now-15m ' }}
|
|
// ];
|
|
|
|
// The result value type will be:
|
|
|
|
// const filter: ({
|
|
// term: {
|
|
// 'agent.name'?: string
|
|
// };
|
|
// range?: undefined
|
|
// } | {
|
|
// term?: undefined;
|
|
// range: {
|
|
// '@timestamp': {
|
|
// gte: string
|
|
// }
|
|
// }
|
|
// })[];
|
|
|
|
// This can sometimes leads to issues. In those cases, we can
|
|
// use `as const`. However, the Readonly<any> type is not compatible
|
|
// with Array<any>. This function returns a mutable version of a type.
