Certified Associate JavaScript Programmer study plan

Map the vendor-neutral certification scope by listing every exam objective area and marking each as known, shaky, or unknown

Set up a local practice environment with a current Node.js LTS runtime and a browser console for running snippets

Write and run 20 small programs covering var, let, const declarations and temporal dead zone behavior

Explain in your own notes the difference between primitive and reference values, including copy semantics

Implement 15 exercises using arithmetic, comparison, logical, and nullish coalescing operators, predicting results before running

Demonstrate type coercion rules for == versus === across at least 12 value pairs and record outcomes

Write functions using default parameters, rest parameters, and spread syntax

Trace closure behavior by building three counter-style examples and predicting output before execution

Build and manipulate arrays using map, filter, reduce, find, some, and every on realistic data

Create objects with literals, computed keys, shorthand properties, and destructure nested structures

Explain prototype chains by constructing inheritance with constructor functions and with Object.create

Use JSON.parse and JSON.stringify including replacer and reviver arguments

Describe the event loop phases and predict output order for mixed synchronous, microtask, and timer code

Write 10 snippets combining setTimeout, Promise callbacks, and queueMicrotask with predicted ordering

Demonstrate promise chaining, error propagation, and async/await with try/catch

Convert three callback-based functions into promise-returning and async versions

Implement error handling with try/catch/finally, custom Error subclasses, and rethrow patterns

Demonstrate this binding rules across method calls, standalone calls, arrow functions, and explicit bind/call/apply

Explain strict mode effects on assignment, this, and duplicate parameters with runnable examples

Use Symbol, iterators, and generators to build a custom iterable collection

Implement classes with inheritance, static members, getters and setters, and private fields

Apply module syntax with named and default exports and explain import hoisting behavior

Demonstrate destructuring in function signatures and nested default value fallbacks

Review weak areas from the week 1 gap list and rewrite notes for the five weakest items

Complete a timed 60-question practice set drawn from your own notes and record per-area accuracy

Re-derive answers for every missed item and write a one-line rule for each mistake

Practice reading code aloud and predicting output for 15 snippets under a two-minute limit each

Drill the five weakest objective areas identified by practice accuracy

Re-run two full timed practice sets and compare accuracy against week 7 results

Review the mistake log and confirm each rule can be stated without notes

Write a one-page summary of coercion, this binding, event ordering, and prototype rules

Simulate exam conditions with a final timed set and no reference material
