1. The js engine performs syntax analysis when the code is loaded. If the JavaScript code is not standardized, the syntax analysis will fail. This error is called a syntax error.
2. After the syntax analysis is passed, the js engine executes the code. An error occurred during execution is called a running error.
Different engines have different prompts for handling these two types of errors. As follows:Copy codeThe Code is as follows: var p = {name:
