If you can teach npm exec command (in node js) using install express, you know it. If you only know the heading, you don’t.

Without npm exec command (in node js), a new folder gets messy and install express is hard to trust.

npm exec command (in node js) shows up in a new folder. Name install express, not “a real-world scenario”.

Don’t do this with npm exec command (in node js): deleting package-lock blindly. Interviewers spot it in ten seconds.

npm exec command (in node js) is not a lonely heading. Priya ties it to install express.

Close npm exec command (in node js) with: “If I skip it, install express goes wrong like this: deleting package-lock blindly.”

Exam tip

Say npm exec command (in node js) in one breath, then npm init + npm i express, then deleting package-lock blindly.

Example

const pkg = {
  name: "demo",
  version: "1.0.0",
  scripts: { start: "node index.js" },
  dependencies: { express: "^4.19.0" },
};
console.log(pkg.name, Object.keys(pkg.dependencies));
