在Visual Studio Code中启用JavaScript IntelliSense遇阻求助

• CSS、HTML等语言的代码片段自动填充、格式规范及拼写检查功能在VS Code中均可正常使用，但JavaScript的代码自动填充功能始终无法生效，尽管已经安装了所有能想到的JavaScript相关扩展。
• 已查阅本站相关帖子尝试解决，但所有方法均无效，希望有类似经历的用户提供帮助。

当前settings.json配置 #

{
    "[python]": {
        "editor.formatOnType": true
    },
    "cmake.configureOnOpen": true,
    "workbench.colorTheme": "Sapphire (Dim)",
    "css.styleSheets": [],
    "javascript.suggest.alwaysAllWords": true,
    "javascript.suggest.completeFunctionCalls": true,
    "[html]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[css]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "emmet.includeLanguages": {
        "javascript": "javascriptreact"
    },
    "emmet.triggerExpansionOnTab": true,
    "enableTelemetry": false,
    "bracket-pair-colorizer-2.depreciation-notice": false,
    "workbench.startupEditor": "none",
    "[javascript]": {
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
}

已尝试的无效配置 #

"emmet.includeLanguages": {
  "javascript": "javascriptreact"
},
