import { function error(status: number, body: App.Error): never (+1 overload)
Throws an error with a HTTP status code and an optional message.
When called during request handling, this will cause SvelteKit to
return an error response without invoking handleError.
Make sure you’re not catching the thrown error, which would prevent SvelteKit from handling it.
@paramstatus The HTTP status code. Must be in the range 400-599.
@parambody An object that conforms to the App.Error type. If a string is passed, it will be used as the message property.
@throwsHttpError This error instructs SvelteKit to initiate HTTP error handling.
@throwsError If the provided status is invalid (not between 400 and 599).error } from '@sveltejs/kit';

':'.String.charCodeAt(index: number): number
Returns the Unicode value of the character at the specified location.
@paramindex The zero-based index of the desired character. If there is no character at the specified index, NaN is returned.charCodeAt(0).Number.toString(radix?: number): string
Returns a string representation of an object.
@paramradix Specifies a radix for converting numeric values to strings. This value is only used for numbers.toString(16); // '3a', hence '[x+3a]'
