SyntaxErrorSyntaxError
The JavaScript engine encountered code that does not conform to the language syntax.
InternalError: too much recursionFirefox-specific error equivalent to RangeError: Maximum call stack size exceeded in Chrome/Node.js.
Identical to the maximum call stack error: a function recurses infinitely or too deeply. Firefox uses InternalError instead of RangeError for this condition.
Add a proper base case to recursive functions. Convert deep recursion to iterative approaches. Check for circular references in object structures. This fix applies identically across all browsers.
SyntaxErrorThe JavaScript engine encountered code that does not conform to the language syntax.
SyntaxError: Unexpected end of inputThe parser reached the end of the input while still expecting more code, usually due to unclosed brackets or strings.
TypeError: x is not iterableA value that is not iterable was used where an iterable was expected, such as in a for...of loop or spread operator.
TypeError: Cannot assign to read only propertyAn attempt was made to write to a property that is read-only, either because the object is frozen or the property is defined as non-writable.
RangeErrorA value is not within the expected range, such as an invalid array length or exceeding the call stack size.
CORS Error: No Access-Control-Allow-OriginThe browser blocked a cross-origin request because the server did not include the required CORS headers.
