package.json

{
"scripts": {
        "prepare:bad-i18n": "yarn -s eslint -c index.js \"**/file-suites/**/bad.json\" > ./out/eslint.bad-i18n.report.txt || exit 0",
        "prepare:bad-ts": "yarn -s eslint -c index.js \"**/file-suites/*.bad.ts\" > ./out/eslint.bad-file.report.txt || exit 0",
        "prepare:good-i18n": "yarn -s eslint -c index.js \"**/file-suites/**/good.json\" > ./out/eslint.good-i18n.report.txt",
        "prepare:good-ts": "yarn -s eslint -c index.js \"**/file-suites/*.good.ts\" > ./out/eslint.good-file.report.txt",
        "prepare:report-file-pattern": "yarn -s eslint -c index.js \"**/file-suites/file-pattern/**/*.ts\" > ./out/eslint.file-pattern.report.txt || exit 0",
        "prepare:report-i18n": "yarn prepare:good-i18n && yarn prepare:bad-i18n",
        "prepare:report-ts": "yarn prepare:good-ts && yarn prepare:bad-ts",
        "prepare:report": "yarn prepare:report-ts && yarn prepare:report-i18n && yarn prepare:report-file-pattern",
        "prepare:folder": "rm -rf ./out && mkdir ./out",
        "test": "yarn prepare:folder && yarn prepare:report && yarn -s jest --config ./jest.config.js"
    }
}

in fact, such a file is not very convenient

Please describe the desired behavior.

"scripts": {
         "test": [
           "yarn prepare:folder",
           "yarn prepare:report"
           "yarn -s jest --config ./jest.config.js"
         ],
         "prepare:folder": [ 
            "rm -rf ./out", 
            "mkdir ./out"
          ],
          "prepare:report": [
              "yarn -s eslint -c index.js \"**/file-suites/*.good.ts\" > ./out/eslint.good-file.report.txt",
              "yarn -s eslint -c index.js \"**/file-suites/*.bad.ts\" > ./out/eslint.bad-file.report.txt || exit 0",
              "yarn -s eslint -c index.js \"**/file-suites/**/good.json\" > ./out/eslint.good-i18n.report.txt",
              "yarn -s eslint -c index.js \"**/file-suites/**/bad.json\" > ./out/eslint.bad-i18n.report.txt || exit 0",
              "yarn -s eslint -c index.js \"**/file-suites/file-pattern/**/*.ts\" > ./out/eslint.file-pattern.report.txt || exit 0"
           ]
    }
}

Thus, if the npm run scriptName[index] could recognize the array, it would be easier to describe some commands

$ npm run prepare:folder # analogue "rm -rf ./out && mkdir ./out"
// or
$ npm run prepare:folder --index 0 "rm -rf ./out"
$ npm run prepare:folder --index 1 "mkdir ./out"
