const path = require(‘path’); path.parse(‘/home/user/dir/file.txt’); // Returns: // { root: ‘/’, // dir: ‘/home/user/dir’, // base: ‘file.txt’, // ext: ‘.txt’, // name: ‘file’ } Here is what the above code is Doing: 1. We’re requiring the path module. 2. We’re calling the parse method on the path module. 3. We’re passing the path to the…
var Str = “Hello There!” var SplitOn = ” ” var Results = Str.split(SplitOn); //Results[0] will be ‘Hello’ and Results[1] will be ‘There!’ Here is what the above code is Doing: 1. We create a variable called Str and set it equal to the string “Hello There!” 2. We create a variable called SplitOn and…
