Modern JavaScript & TypeScript
Build the language fluency every web and Node course assumes: modern JavaScript semantics, the event loop, module systems, and a working TypeScript type discipline. Learners finish able to read and write typed application code, explain why an async result arrived in the order it did, and defend a bundler and test setup they configured themselves.

Roles this course serves
This course is authored to band B2.
Every course we run is written to one rung of the CASI ladder, so a plan can be assembled to take a team from where they are to where they need to be.
What do B1–B6 mean?The CASI Capability Ladder — click to expand
Every course targets a band on the CASI Capability Ladder — our six-band proficiency scale, anchored to open standards (O*NET, ESCO, NICE, NIST AI RMF, Bloom's). A band tells you how deep a course goes, and what evidence proves it.
A note on B6. Courses in this catalog target B1–B5. B6 is not taught — it is recognised, through a portfolio and a panel, once someone is setting direction for others. Every journey here is built to land a learner at B5.
