How can I replace an occurrence of a string embedded in a symbol, storing the result of the transformation in a string?

In Javascript, there's a simple way to replace a string embedded in another string, as documented at 

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

. Here's a simple example, which works in Javascript for Max :

oldText = "The quick brown fox jumps over the lazy dog.";

newText = oldText.replace("fox", "deer");

// newText should now be "The quick brown deer jumps over the lazy dog."

But if the string to be replaced is embedded in a Max symbol instead of another string, this method does not work. Evidently Max's symbol data type does not support string functions such as Replace. For example:

newText = this.patcher.path.replace("/patchers", "/data");

// Javascript TypeError: this.patcher.path.replace is not a function

Any suggestions? If there's a way to convert a symbol to a string, I could modify the above example to make it work.

I've worked it out. The problem is specific to "patcher.path" which turns out to be neither a valid property not a valid method of the Patcher object. Here's my fixed code:

patchersFolderPath = this.patcher.filepath.replace("/" +  this.patcher.name + ".maxpat", "");
datafolderPath = patchersFolderPath.replace("/patchers", "/data");

What I wrote above about strings versus symbols turns out to have been nonsense.
