JavaScript 优化：简化空数组判断条件

{"title":"if (user.length != 0 || copy.length != 0) {\n console.log();\n } 帮我优化下内容：if (user.length !== 0 || copy.length !== 0) {\n console.log();\n}\n```\nThis code appears to be checking if either the user or copy variables are empty. The condition user.length !== 0 and copy.length !== 0 can be simplified as user.length and copy.length will implicitly be evaluated as true if they are not equal to 0. Therefore, the optimized code can be written as:\n\nif (user.length || copy.length) {\n console.log();\n}\n
