Reservoir sampling, randomised pivots, and using randomness to dodge an adversarial worst case.

Animating on the compositor, avoiding layout thrash, and honouring reduced-motion preferences.

Cache-aside, write-through, TTLs, stampedes, and the invalidation everyone quotes about.

Location ingest at high write volume, proximity search, matching, and state machines for a trip.

Hashing versus encryption versus signing, choosing a primitive, and never writing your own.
Listed inWhat Seniority Actually MeansWorking as an Engineeron
Scope, judgement, and multiplying other people — none of which is measured in years or languages.

A structural type system over JavaScript, erased at build time — now the default for new web codebases.
Listed inPersistent Data StructuresData Structures & Algorithmson
Structural sharing so an "update" returns a new version cheaply, without copying the whole thing.

The two properties that predict how expensive your next change will be.
Listed inResponsive DesignFrontend Engineeringon
Fluid type and space, container queries, and designing from content outwards rather than from breakpoints in.
Listed inRelational ModellingDatabaseson
Keys, relationships, normalisation, and knowing which normal form to stop at.
Listed inPush vs Pull DeliverySystem Designon
Fan-out on write against fan-out on read, and the celebrity problem that breaks whichever you picked.
Listed inUnit TestsTestingon
Testing behaviour rather than implementation, so a refactor does not turn the suite red.
Listed inDebugging in ProductionObservability & Operationson
Forming a hypothesis, narrowing with the tools you have, and resisting the fix you cannot explain.
Listed inDates, Times, and ZonesComputing Foundationson
UTC as the only sane storage format, offsets versus zones, DST gaps, and leap seconds.

The web's original glue language. You will meet it in scripts nobody has opened since 2009.
Listed inChoosing a Data StructureData Structures & Algorithmson
Starting from the access pattern rather than the structure, and why a plain array usually wins.
