title: Under standingrelative and abolute path javascript
body: <p>Can someone please help me with understanding concept of relative and absolute paths. I am really confused how they work in what directory I am ? 
  I have this following code I can't include  PostService module.</p>
  
  <pre><code>import { Component } from '@angular/core';
  import { PostService } from '../services/post.service';
  
  @Component({
  moduleId: module.id,
  selector: 'search',
  templateUrl: 'search.component.html',
  providers:[PostService]
  })
  
  export class SearchComponent  { 
      posts: post[];
  
      constructor(){
                  this.posts = [
          {
              id: 1,
              title:"Post heading",
              body: "They want a self-starter. They don't need more handholding than necessary. They want someone whos not a script kiddy, who knows solid software engineering fundamentals. They want someone who will work well with the team, and be proactive in improving the situation, rathe t just playing the victim when things go wrong."
          },
                      {
              id: 2,
              title:"Post heading",
              body: "They want a self-starter. They don't need more handholding than necessary. They want someone whos not a script kiddy, who knows solid software engineering fundamentals.
