Question 1

What Web Legacy and JavaScript training courses does JBI Training offer?

Accepted Answer

JBI Training offers twelve courses in this group covering established and foundational web technologies and JavaScript at all levels. Available courses include JavaScript and ECMAScript (three days), JavaScript Intermediate (three days), JavaScript Advanced (three days), JavaScript with Node Beyond the Basics (two days), ECMAScript 6 Introduction (three days), CSS Cascading Style Sheets (two days), jQuery (two days), MongoDB (two days), Backbone.js (two days), Aurelia (three days), Google Polymer.js (three days), and Ext JS (four days). All courses are available as scheduled classroom sessions in London, as live online instructor-led training, or as customised onsite programmes for web development teams.

Question 2

Why are JavaScript fundamentals still important in an era of modern frameworks?

Accepted Answer

JavaScript frameworks such as React, Angular, and Vue abstract many details of how JavaScript works, but developers who lack solid JavaScript fundamentals frequently struggle to debug framework code, understand performance issues, or work effectively beyond the patterns the framework provides. A strong grounding in core JavaScript — including the event loop, closures, prototypal inheritance, asynchronous programming with promises and async/await, and the module system — is the foundation that makes developers more effective with any framework or library they use. JBI's three-level JavaScript curriculum (introductory, intermediate, and advanced) is designed to build this foundation systematically regardless of which front-end framework a developer ultimately works with.

Question 3

What is ECMAScript and what does the ECMAScript 6 course cover?

Accepted Answer

ECMAScript is the specification that defines the JavaScript language — the version numbers (ES5, ES6, ES2020, etc.) refer to successive editions of that specification. ECMAScript 6 (also known as ES2015) was the most significant update to JavaScript in over a decade, introducing arrow functions, classes, template literals, destructuring, the spread and rest operators, modules, Promises, let and const declarations, and many other features that are now foundational to modern JavaScript development. JBI's three-day ECMAScript 6 Introduction course covers all of the major ES6 features in depth, with practical exercises applying each feature in realistic web development scenarios. It is suited to JavaScript developers who learned the language before ES6 and want to modernise their skills.

Question 4

What is MongoDB and what does the MongoDB training course cover?

Accepted Answer

MongoDB is the most widely used document-oriented NoSQL database. Unlike relational databases that store data in tables and rows, MongoDB stores data as flexible JSON-like documents — making it well-suited to applications with variable or evolving data structures, high write throughput requirements, or hierarchical data. JBI's two-day MongoDB course covers the MongoDB architecture and document model, CRUD operations, querying and indexing, the MongoDB aggregation pipeline for data analysis, schema design patterns, replication and high availability, and integrating MongoDB with Node.js applications. It is suited to developers and data engineers building or working with MongoDB-backed applications.

Question 5

What is jQuery and is it still relevant for web development?

Accepted Answer

jQuery is a JavaScript library that simplifies DOM manipulation, event handling, AJAX requests, and animation across different browsers. It was the dominant JavaScript library for web development for many years and is still present in a very large number of websites and web applications worldwide — including many maintained enterprise and government systems. While modern frameworks have reduced the need for jQuery in new greenfield development, jQuery skills remain highly relevant for developers maintaining, upgrading, or extending existing codebases that rely on it. JBI's two-day jQuery course covers selecting and manipulating DOM elements, handling events, making AJAX calls, working with jQuery plugins, and integrating jQuery with other web technologies.

Question 6

What is CSS and what does the CSS training course cover?

Accepted Answer

CSS (Cascading Style Sheets) is the language used to control the visual presentation of web pages — including layout, typography, colour, spacing, and responsive behaviour across different screen sizes. JBI's two-day CSS course covers the CSS box model, selectors and specificity, positioning and layout techniques including Flexbox and CSS Grid, responsive design with media queries, CSS variables and custom properties, transitions and animations, and best practices for writing maintainable and scalable CSS. It is suitable for web developers, designers, and anyone responsible for the front-end presentation of websites and web applications who wants to build or consolidate their CSS skills.

Question 7

Can web classic and JavaScript training be customised for a corporate development team?

Accepted Answer

Yes. All courses in this group can be delivered as customised onsite or online programmes for corporate web development teams. Content and exercises can be tailored to the team's technology stack, existing codebase, and specific learning objectives — for example, a team maintaining a large legacy jQuery-based application can receive training focused on jQuery patterns and modernisation strategies, while a team building Node.js backend services can receive JavaScript and Node training focused on their specific architecture. JBI has delivered web development training for engineering teams at organisations including the BBC, NHS, RBS, Sky, EDF, and Cisco.

Question 8

Are web classic and JavaScript courses kept up to date with the latest language and ecosystem changes?

Accepted Answer

Yes. JavaScript and its ecosystem evolve continuously with new ECMAScript specifications released annually, and JBI's JavaScript training content is regularly reviewed to reflect the latest stable language features, current best practices, and modern tooling. This includes updates to JavaScript syntax and APIs, Node.js runtime developments, changes to the CSS specification including new layout and styling capabilities, and the evolving relationship between foundational JavaScript skills and AI-assisted coding tools such as GitHub Copilot and Claude Code — where strong JavaScript fundamentals are increasingly important for evaluating and steering AI-generated code effectively.

Question 9

Are these courses available online?

Accepted Answer

Yes. All JBI Training courses run as live online instructor-led sessions as well as in-person in London and as bespoke on-site training at your organisation.

Question 10

Can these courses be customised for my team?

Accepted Answer

Yes. All JBI Training courses can be delivered as bespoke closed-group programmes tailored to your team's technology stack, experience level, and business objectives. Contact enquiries@jbinternational.co.uk.
