JavaScript Programming Fundamentals: Free Course

About this course

Study JavaScript Programming Fundamentals through this free English video course from freeCodeCamp. The classroom brings together all 36 public recordings from the selected source curriculum, totaling approximately 3h 0m. You can watch the teaching sequence, search the lesson list and keep track of the recordings you have completed. The course focuses on the subject named in its title. Its value comes from following the explanations and making your own small practice attempts, with enough time to inspect the result and explain the decisions involved.

Course Overview

Thirty-six ordered lessons cover types, control flow, arrays, objects, asynchronous concepts, errors and dates.

The source lesson list includes “Variables – Beau teaches JavaScript”, “For Loops – Beau teaches JavaScript”, “Dates – Beau teaches JavaScript”. The classroom retains their original titles and positions. Introductions, supplementary explanations and complete-course recordings remain present whenever they are part of the source. A repeated recording is retained at each original position, allowing the course to be checked against the published teaching sequence.

Language foundations

Start with variables, types, numbers and strings. Predict the result of a short expression before running it, and explain how the values and operators determine the output.

Decisions and repetition

Follow functions, comparison, logical operators, conditionals and loops. Trace one ordinary input and one edge case, keeping the stopping condition visible.

Collections and objects

Study arrays, iteration methods and objects. Compare a transformation with its input and explain what changes when an operation returns a value or updates existing information.

Further language tools

Follow Ajax, JSON, closures, this, promises, timing, strict mode, errors and dates. Connect each concept with the example in the recording and revisit the prerequisite syntax when needed.

Who is this for?

This course suits learners who want the specific subject described above and who can work at the stated level. It is also useful as a recorded reference when revisiting a concept or comparing a practice attempt with a demonstrated example. Beginners should give the foundational explanations time before moving to more elaborate applications. Experienced learners can use the lesson names to locate a topic, then inspect the surrounding context before applying a technique.

Before you start

The course begins with fundamentals. A browser console or JavaScript runtime is useful for practice. HTML knowledge helps with browser examples but is not needed to trace the introductory language calculations.

Put the lessons into practice

Create a fictional book-summary program using an array of records. Write a function that filters the entries and returns a small summary. Test an empty array and an unexpected value, then explain the conditional and iteration steps. Add one timed or asynchronous mock operation using sample data. Keep a note of how errors are handled and which values the function returns.

Treat this suggested exercise as independent practice provided by WikiFree. Keep a short working note containing your inputs, assumptions, result and one point you still need to check. Revisit the relevant recording when a step is unclear, then attempt a small variation without following the demonstration line by line. A result you can explain and reproduce is a more useful study outcome than simply recognizing a familiar term. The exercise is not submitted to an instructor for grading.

Certificate / Assessment

Watching these public recordings and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. The video curriculum is the material included here. Separate platform assignments, credentials and paid services are not part of video viewing. Use the practice output to review which concepts you can explain, which steps you can repeat independently and which questions need another look at the teaching.
