Add type guard to isLocaleNameSane() to prevent runtime crashes on non-string input.
The function calls name.match() without checking if name is a string. Non-string values (e.g., from moment.locale() called with numeric or boolean arguments) will throw a TypeError at line 1847 before the try/catch in loadLocale() can handle it.
Suggested fix
function isLocaleNameSane(name) {
// Prevent names that look like filesystem paths, i.e contain '/' or '\'
- return name.match('^[^/\\\\]*$') != null;
+ return typeof name === 'string' && /^[^/\\]*$/.test(name);
