Fundamentals of testing involve understanding the purpose, techniques, and principles of software testing.

• Testing is done to identify defects and ensure quality

• Techniques include black box, white box, and grey box testing

• Principles include exhaustive testing is impossible, early testing, and defect clustering

• Testing should be planned, designed, executed, and evaluated

Different approaches of testing include black box testing, white box testing, regression testing, and exploratory testing.

• Black box testing focuses on the functionality of the software without knowledge of its internal code.

• White box testing examines the internal code and structure of the software.

• Regression testing ensures that new code changes do not adversely affect existing functionality.

• Exploratory testing involves simultaneous learning, test design, and test execution.

Closures in JavaScript are functions that have access to variables from their outer scope even after the outer function has finished executing.

• Closures allow for maintaining state in an asynchronous environment

• They are created whenever a function is defined within another function

• Example: function outerFunction() { let outerVar = 'I am outer'; return function innerFunction() { console.log(outerVar); }; }
