One way developers describe the usability of JavaScript libraries is how compatible they are with other libraries. The more libraries your library plays well with, the more likely it can be used on projects. When libraries don't play well with other libraries and frameworks, it can lead to unintended code bugs and actions that nobody saw coming. Since a developer cannot control what other libraries are used in a project with their library, it is better if a library plays well with others.
There are several ways that libraries can conflict with one another. One way that was more common in the past is through namespace collision. If two libraries create the same cut()
function in the global namespace, you can't be sure which one will be called. Another, more subtle conflict arises through manipulating the prototype of standard JavaScript types. One library will expect the map()
method called on an array to perform a specific task, but if another...
