JavaScript Complete Course – Basics to Advanced | 15+ Tests

Explore variable declarations and dynamic typing in JavaScript, a loosely typed language. Learn about scope, global versus local, and use strict for safer code.

Explore JavaScript operators and control statements, including arithmetic and equality operators, the difference between == and ===, operator precedence, and error handling with try, catch, and finally.

Explore how JavaScript arrays work, including dynamic length, indexing, and multiple declaration methods, and master common operations such as push and shift, slice, sort, reverse, join and split.

Master the basic syntax of JavaScript functions, using the function keyword, a name, and a parameter list, with arguments, default values, and undefined checks, noting no overloading.

Explore predefined functions and built-in classes in JavaScript, learn to evaluate expressions with eval, convert strings to numbers across bases, and apply ASCII encoding and percent-escape sequences for dynamic strings.

Explore JavaScript date and time functions by creating and formatting date objects, obtaining system time in local and GMT formats, and understanding epoch milliseconds since 1970.

Master JavaScript string handling with built-in methods such as indexOf, lastIndexOf, substring, slice, split, trim, toUpperCase, and toLowerCase, plus regular expressions for search and replace.

Discover the JavaScript math object and its essential functions for performing number operations, including random number generation, max and min, absolute value, floor and ceil, and exponential constants.

Explore the JavaScript document object model as it shows how form elements become objects with properties, events, and methods to access, update values, and apply styles.

Explore form elements such as radio buttons, select lists, and text inputs, implement on-change logic to perform add, subtract, multiply, and divide operations, and manage selected options and values.

Learn client-side form validation in JavaScript: validate inputs before submission, prevent submission on invalid data, and manage events and form element collections to handle text fields and checkboxes.

Explore the window object in JavaScript, its properties, methods, and events; learn to open, configure, move, and close windows, and interact with the opened window's document and setTimeout/setInterval timers.

Explore document object model and its properties, using bracket and dot notation to access values. See how to manipulate images, links, and events with the event object and current element.

Explore the remaining dom objects, especially history and location, to implement back and forward navigation and page replacement. Learn to manage user-agent, window properties, and link targets for browser behavior.

Learn how to manage client-side state in JavaScript by creating, reading, and deleting cookies, including name-value pairs, domain constraints, expiry, and persistent cookies.

Learn how JavaScript treats non-primitive values as objects, create custom classes or constructors, and build multiple instances with properties and methods like deposit and withdraw.

Understand how the call method assigns this to an object and passes arguments in JavaScript. See how to invoke functions in another object's context, using the window object and arguments.

Learn how JavaScript uses prototypes to simulate inheritance, extend a class with new functionality, and manage current account properties like name, balance, and company name via call and context.

Explore next steps after completing javascript from basic to advanced, with personalized training on a training portal, downloadable materials, case studies, interview questions, and real-time project insights plus certification guidance.
