360° ES training

This course is taught 100% remote

Last updated on October 25, 2021, 11:28pm

The 360° ES training is the only course out there covering 100% of JavaScript’s latest generation features. It was designed to address the trainees that now and then came to us saying something like “I love the first day of your Node.js / Modern Web Apps courses, and your conference talks, but what I’m really yearning for is in-depth mastery of the latest features in the language, however niche or obscure”.

Delicious Insights enjoys a solid reputation of expertise on ECMAScript (JavaScript), and we love working with the under-used power of the language, so it only seemed natural to create a training course targeting trainees that want to become their entourage’s absolute go-to person for JS.

Thus was 360° ES born (the inevitable name of which finally triggered the long-deferred rebranding of 360° JS, now Modern Web Apps). In this course, you won’t find a single language aspect uncovered, not a single edge-case left aside... and not only do we cover the language’s latest version, we even explore what’s coming in the few next years! You’re in for three super-dense days: par for the course at DI.

  • 100% up-to-date language coverage
  • Metaprogramming
  • Edge cases
  • Niche aspects
  • Interactive exercices
  • Hidden powers
  • Upcoming features
  • Trainer contributes to JavaScript

Goals

The 360° ES training aims to empower trainees to:

  • Know 100% of latest-generation JavaScript
  • Pick the right syntaxes to improve maintainability and expressiveness
  • Write more idiomatic code by forsaking obsolete approaches
  • Know how to use new data types and protocols (e.g. iterability)
  • Leverage metaprogramming to reduce code quantity
  • Secure code, notably through ES proxies

Intended audience

The 360° ES training targets first and foremost developers who already have a solid JavaScript experience, and wish to gain in-depth mastery of all language aspects, including the most advanced ones.**

A regular practice of JavaScript in actual operational contexts is mandatory, ideally using ES2015+. On the other hand, there is no need whatsoever to already use the language’s more advanced facets (such as custom iterators, proxies, generators, weak maps, etc.): this is what this training is for! You should:

  • Know the fundamentals of JavaScript: variables, data types, loops, functions, the language's standard library at least as of ES3 (1999).
  • Use of JS in production on 10+ diverse scenarios.

Unless otherwise specified, predefined-dates, multi-client sessions are held in French, so attendees should be reasonably fluent. You are naturally welcome to book custom dates for your company using the link above.

Logistics

  • Every session is held synchronously, “live,” including remote sessions. This is not about pre-recorded videos.
  • We are currently not scheduling new multi-client in-room sessions before, at the earliest, April 1st, 2022.
  • Comprehensive course material is provided, acting as a common thread. It usually includes numerous slides and starter codebases or repositories for every exercise and lab.
  • Trainees can ask questions at any time.
  • Sessions always alternate between theory and hands-on labs, in short intervals (5 minutes to 1 hour).
  • Hands-on periods rely on real-world use-cases (which can be bootstrapped through starter codebases, Git repositories or online assignment labs).
  • Hands-on periods may be completed individually or as sub-groups that may vary from one period to the next, to foster pair programming and collaboration.
  • Remote sessions use a Zoom recurring meeting, accessible through a provided link using both the installed app and the pure-web, no-install client. They mostly use features such as video thumbnails, screensharing, chat, breakout rooms and possibly quizzes, annotations and whiteboards.
  • Sessions span 5 consecutive afternoons, adding up to 21 hours of class.
  • The schedule runs from 13:48 to 18:00.
  • For custom dates booked specifically by your company, the schedule can be adjusted to better suit your needs. In particular, we can use half-days locked on reasonable hours in your timezone, e.g. 9a-12:30p EST or 8a-11:30a PST.
  • Every trainee uses their own laptop or workstation.
  • No ahead-of-time setup on your machine is necessary.
  • Training sessions range from 3 to 10 trainees.

Deliverables & assessments

  • Every session half-day requires attendance signing (paper sheet or digital tool). For remote sessions, should a trainee fail to submit their entire attendance sheet in due time, Zoom participant logs will be considered authoritative.
  • At the beginning of every day's first period, we run a “debrief”: during about half an hour, we help collectively resurface skills and knowledge first tackled on the previous day. This helps put everyone back “in the zone,”, consolidate learning and boost group dynamics.
  • Throughout the course, assessment of skill acquisition is done through the successful completion of hands-on labs (exercises, mini-projects, labs, use cases, etc.). Interactive quizzes may supplement this. The trainer remains available for any question during hands-on periods.
  • Should a trainee exhibit significant difficulty, the trainer may opt to provide one-to-one mentoring for a while using the trainee's computer as a working base. This also applies to remote sessions using Zoom's dedicated features (e.g. one-to-one / individual assistance).
  • When the session ends, every trainee may request a completion certificate (or at least attendance certificate) and, for remote sessions financed by a French institutional entity, we issue a standardized completion certificate in order for financing to be able to proceed smoothly.
  • Once the training is over, every trainee receives a link to an online “hot” feedback survey, so they can express, among other things, whether they feel they achieved the stated goals of the training (or believe these will be achieved in the short term).

During the session, trainees receive at the start of every period access to:

  • all the related slides and supporting material in a web-based format, so they can easily follow along,
  • the interactive online lab for hands-on exercises.

Once the training is done, they also get:

  • an extremely content-rich debrief e-mail,
  • a reference archive with all related slides, solutions for all exercises, and various complementary resources.

Acquired skills are assessed throughout the session, by looking at the success rate of online interactive exercises, that leverage step-by-step guidance and automated scoring.

Hardware & software requirements

  • Use a computer of sufficient performance (and provide it for single-client, in-room sessions, so ideally a laptop)
  • Remote sessions: this computer must feature a webcam, mic and audio output.
  • Remote sessions: use an internet connection with sufficient bandwidth (1Mbps+, ideally 5Mbps+), both incoming and outgoing.
  • Remote sessions: be able to run Zoom, either as a desktop install or as the pure-web client. You can test the installed software's configuration here.

Registration & deadlines

Regardless of the modalities you're looking for (single- or multi-client, in-room or remote), your initial request (for quotation or contract) should be made online from the training’s web page. You can find further up contract request links for every available multi-client session, a proposal request button for a single-client session, and for any other enquiry can use the contact button further below. Please favor our online forms as they speed up processing by avoiding numerous e-mail back-and-forths in order for us to get all your necessary information.

For multi-client, fixed-date sessions, we reply to quotation or contract requests within at most 2 business days (and usually within minutes). For single-client, custom sessions, we usually get back to you within 3 business days to fine-tune your requirements and create a bespoke offer.

The e-mails we send to provide quotations or contracts, as well as our online training pages, provide a link to an online survey prospective trainees can use for fit-for-needs assessment; this information should get to us ASAP, ideally before contract signing, so we can verify our training offer is a good match for the audience.

Summons are sent by e-mail no later than 7 days prior to the session, at which time a potential cancellation decision (usually because two few trainees registered) is made. If the session is guaranteed ahead of that deadline, we can send your summons earlier at your request.

For multi-client sessions, you can register online (requesting a contract and sending it back signed by e-mail) until the day before the session starts, provided the required amount of seats remain free. If you finalize your registration after the usual summons-sending deadline, your summons are sent immediately by e-mail.

However, when French nationals contractualize with us in their personal capacity, French law mandates a withdrawal period (10 calendar days for in-room sessions, 14 calendar days for online sessions). In order to allow such clients to register later than this, they are provided an opt-in choice in their contract request online form to waive their withdrawal rights if the schedule requires it.

For French client entities applying for third-party financing (e.g. OPCOs, Pôle Emploi, Regions, EU), it is imperative that financing agreements be sent to Delicious Insights no later than the last day of the training session. Should financing be denied or only partially provisioned, the client is liable for payment of the balance of the fee.
