Reference error while including .js in .html in ubuntu using flask

Question

I am trying to include a str.js and jit.js file in nev.html. Both are in same directories but it is giving me a reference error:

flask file in flask/app1.py

import json
import simplejson
from flask import Flask, render_template, request
app = Flask(__name__)

@app.route('/')
def hello():
    return 'client.html'

@app.route('/returnjson')
def returnjson():
    str1 = json.dumps({"name":"Infinetly Beta","friends":[{"name":"Aamir","friends":[{"name":"Jesal","friends":[]}]},{"name":"Neville","friends":[{"name":"Kapil","friends":[]}]}]})
    return str1

@app.route('/neville')
def index():
    return render_template('nev.html')

if __name__ == "__main__":
     app.run(debug=True)

When I run it using flask, it gives this error:

Keep css and js in a folder under 'static' folder in Flask app root directory. Something like following hierarchy helps:

Flask/static/javascripts/*.js
Flask/static/stylesheets/*.css

and change references in templates and other files.
