    url: string | undefined,

) => StackFrame;

Converts Debugger.CallFrame to Sentry StackFrame

function checkOrSetAlreadyCaught

checkOrSetAlreadyCaught: (exception: unknown) => boolean;

Checks whether or not we've already captured the given exception (note: not an identical exception - the very object in question), and marks it captured if not.
This is useful because it's possible for an error to get captured by more than one mechanism. After we intercept and record an error, we rethrow it (assuming we've intercepted it before it's reached the top-level global handlers), so that we don't interfere with whatever effects the error might have had were the SDK not there. At that point, because the error has been rethrown, it's possible for it to bubble up to some other code we've instrumented. If it's not caught after that, it will bubble all the way up to the global handlers (which of course we also instrument). This function helps us ensure that even if we encounter the same error more than once, we only record it the first time we see it.
Note: It will ignore primitives (always return false and not mark them as seen), as properties can't be set on them. {@link: Object.objectify} can be used on exceptions to convert any that are primitives into their equivalent object wrapper forms so that this check will always work. However, because we need to flag the exact object which will get rethrown, and because that rethrowing happens outside of the event processing pipeline, the objectification must be done before the exception captured.
Parameter A
thrown exception to check or flag as having been seen
Returns
true if the exception has already been captured, false if not (with the side effect of marking it seen)

function consoleSandbox

consoleSandbox: <T>(callback: () => T) => T;

Parameter callback
The function to run against the original console messages
Returns
The results of the callback

function convertToPlainObject

    value: V
) =>
    | V
    | {
          [ownProps: string]: unknown;
          type: string;
          target: string;
          currentTarget: string;
          detail?: unknown;
      }
    | { [ownProps: string]: unknown; message: string; name: string; stack?: string };

Transforms any Error or Event into a plain object with all of their enumerable properties, and some of their non-enumerable properties attached.

Reason: DOM/querySelector is not available in all environments.
We have to cast to any because utils can be consumed by a variety of environments, and we don't want to break TS users. If you know what element will be selected by document.querySelector, specify it as part of the generic call. For example, const element = getDomElement<Element>('selector');

JSDoc

function loadModule

loadModule: <T>(moduleName: string) => T | undefined;

Helper for dynamically loading module that should work with linked dependencies. The problem is that we _should_ be using require(require.resolve(moduleName, { paths: [cwd()] })) However it's _not possible_ to do that with Webpack, as it has to know all the dependencies during build time. require.resolve is also not available in any other way, so we cannot create, a fake helper like we do with dynamicRequire.
We always prefer to use local package, thus the value is not returned early from each try/catch block. That is to mimic the behavior of require.resolve exactly.

module name to require
Returns
possibly required module
