10 - Test if a Value Falls in Specific Range - Quality Assurance with Chai - freeCodeCamp Tutorial

There are many use cases where we need to check approximate equality. We can use Chai's approximately() method to do this. We provide an input (actual) value, a target (expected) value, and a variance (delta) to form the range around the target value which we can specify as approximately equal.

02:28 - Challenge Solution -————————————————————————————————————- Chai is an assertion library, similar to Node's built-in assert. It makes testing much easier by giving you lots of assertions you can run against your code.

freeCodeCamp (also referred to as “Free Code Camp”) is a non-profit organization that consists of an interactive learning web platform, an online community forum, chat rooms, online publications and local organizations that intend to make learning web development accessible to anyone. Beginning with tutorials that introduce students to HTML, CSS and JavaScript, students progress to project assignments that they complete either alone or in pairs. Upon completion of all project tasks, students are partnered with other nonprofits to build web applications, giving the students practical development experience.
