Expand description

Checks for syntax errors in a string of JavaScript.

  • ctx: The execution context to use.
  • script: A JSStringRef containing the script to check for syntax errors.
  • sourceURL: A JSStringRef containing a URL for the script’s source file. This is only used when reporting exceptions. Pass NULL if you do not care to include source file information in exceptions.
  • startingLineNumber: An integer value specifying the script’s starting line number in the file located at sourceURL. This is only used when reporting exceptions. The value is one-based, so the first line is line 1 and invalid values are clamped to 1.
  • exception: A pointer to a JSValueRef in which to store a syntax error exception, if any. Pass NULL if you do not care to store a syntax error exception.

Returns true if the script is syntactically correct, otherwise false.
