JSLint：对象数组中出现意外的']'

Question

I'm using JSLint in PHPStorm with ES6 and I have this error after the line : pathPublic + "/css/style.css",

JSLint: Unexpected ']'.

My code :

    let filesCss = [
    {
        outputFilename: "fc-main.min.css",
        outputPath: pathPublic + "/css",
        inputFiles: [
            pathPublic + "/css/style.css",
        ],
    },
];

Answer 1

The trailing commas can hisotrically give issues on older IE versions:

The "Extra comma. (it breaks older versions of IE)" error (and the alternative "Trailing comma" and "Unexpected ',' errors") are thrown when JSLint, JSHint and ESLint encounter a comma following the final element of an array literal or a comma following the final value in an object literal. Since version 2.0.0 JSHint will only raise this warning if the es3 option is set to true.

So you have to remove them or use the es<version> option:

    let filesCss = [
    {
        outputFilename: "fc-main.min.css",
        outputPath: pathPublic + "/css",
        inputFiles: [
            pathPublic + "/css/style.css"
        ]
    }
];
