 The result of `DeminifyStackTrace` is a `DeminifyStackTraceResult`, which is an object that contains a list of the parsed minified `StackFrame` objects in the `MinifiedStackFrame` property. The `DeminifiedStackFrame` property contains the best guess `StackFrame` object that maps to the `MinifiedStackFrame` element with the same index. Note that any of the properties on a `StackTrace` object may be null if no value could be extracted from the input callstack string or source map.
 
 #### Memory Consumption
-Parsed soure maps can take up a lot of memory for large JavaScript files. In order to allow for the `StackTraceDeminifier` to be used on servers with limited memory resources, the `StackTraceDeminfierFactory` exposes a `GetMethodNameOnlyStackTraceDeminfier` method that returns a `StackTraceDeminifier` that does not keep source maps in memory. Since the `StackTraceDeminifier` returned from this method only reads the source map once, the deminfied stack frames will only contain the deminified method name and will not contain the original source location.

 ## Remarks
 Browsers return one based line and column numbers, while the source map spec calls for zero based line and column numbers. In order to minimize confusion, line and column numbers are normalized to be zero based throughout the library.
