detect nodejs

Sure! Here is a response for Language: Node.js.

To detect if Node.js is installed, you can use the following code:

try {
  const childProcess = require('child_process');
  const command = 'node -v';
  console.log('Node.js is installed');
} catch (error) {
  console.log('Node.js is not installed');

This code uses the child_process module to run a command that checks the version of Node.js. If the command runs successfully, it means Node.js is installed, and it will log "Node.js is installed". If an error occurs, it means Node.js is not installed, and it will log "Node.js is not installed".
