First of all: script in head? Second: put jquery first yeah, after that the bootstrapand your own as last one Have you taken a look at this: https://v4-alpha.getbootstrap.com/getting-started/introduction/#quick-start ? — Nebulosar, Oct 06 '17 at 06:46

@starosacompany, not wrong, it's just a better pratice to put it at the bottom of your page, so that the js renders after the page is shown instead of before — Nebulosar, Oct 06 '17 at 06:51

add your external files as follows

you can add js files in header or in footer but maintain this order

Load Jquery first and then add bootstrap js

i solve it by removing the "integrity code part" . may i know whats the use of that part ? — sta rosa company, Oct 06 '17 at 06:59
refer this for integrity https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script its mainly for `CDNs` not needed for local files. — Znaneswar, Oct 06 '17 at 07:03
before loading bootstrap.min.js you need to load jquery and then follow the bootstrap's order — Znaneswar, Oct 06 '17 at 07:05

Uncaught Error: Bootstrap's JavaScript requires jQuery. jQuery must be included before Bootstrap's JavaScript. at bootstrap.min.js:6
