Question

I am using nodejs and I get an array using walksync i.e.

var paths = ['Essential Classes.jade' , 'introduction.jade']

These are filenames inside a folder. Now i want only filename but not extension, So I have to split every string in array. But don't know how.I want the result like below

['Essential Classes' , 'introduction']

You can do

var paths = ['Essential Classes.jade' , 'introduction.jade'];

paths = paths.map(e => e.replace(/\.\w+$/, ''));

console.log(paths);

You can use map to split each string in the array and get the first string, which is the file name:

1- Using an arrow function:

var paths = ['Essential Classes.jade' , 'introduction.jade'],

paths = paths.map((str) => str.split('.')[0]);
console.log(paths);

2- Using a normal function:

var paths = ['Essential Classes.jade' , 'introduction.jade'],

paths = paths.map(function(str) { return str.split('.')[0] });
console.log(paths);

use . each to iterate the array
use split() to split the array value then get first index

var paths = ['Essential Classes.jade', 'introduction.jade'];

var arr = [];


$.each(paths, function(i,v) {

  arr.push(v.split(".")[0])

})

console.log(arr)
