With hundreds or thousands of lines of code, it's no question that splitting code in different files can help make it more manageable. Although, this can quickly turn into a complicated mess if the splitting isn't thought out beforehand. This video explains how browsers are able to interpret splits from languages like JavaScript and provides best practices based on those behaviors.
We can end up with hundreds or thousands of lines of code very quickly.…And although we will be splitting them up into functions, they can still get…difficult to read and navigate.…Another way to make your code more manageable-- and this happens in every…programming language--…is we stop trying to keep it all in one file and we just split it up…into several files.…Now you wouldn't do this randomly.…You wouldn't have half a function in one file and half in the other.…But you might group several functions together in one file and several more in another.…This also makes it easier for multiple people to work on the same project by…working on separate files.…
And in complex applications built by teams of software developers, it's not…unusual to have hundreds or thousands of separate code files for one project.…Now JavaScript isn't a language that you would want to split up into hundreds…or thousands of files.…It's unusual to have more than a handful.…The question is if you do split it up, how does the web page know where to find everything?…
