If a path exists between two nodes in the graph, then the graph is connected. This means that there is a path between any two nodes in the graph, and that the graph is not acyclic.
var path = require('path');
if (path.existsSync('/etc/passwd')) {
console.log('Path exists.');
} else {
console.log('Path does not exist.');
}
The first line creates a variable called path that requires the ‘path’ module. The ‘path’ module is a core Node.js module that provides utilities for working with file and directory paths.
The second line checks if the ‘/etc/passwd’ path exists. If it does, the ‘Path exists.’ message is logged to the console. If it does not, the ‘Path does not exist.’ message is logged to the console.
