JavaScript runtime errors are errors that result when a JavaScript script attempts to perform an action that the system cannot run. When a JavaScript run-time error occurs when a script is running, a variable expression is evaluated, or memory is being dynamically allocated. JavaScript syntax errors are errors that result when a JavaScript statement violates one or more grammar rules of the JavaScript scripting language. JavaScript syntax errors occur during the program compilation phase before you start running the program.
