In our renaming directory you'll see the same module system as in the previous example, except that we've added circle.js and triangle.js modules to draw and report on circles and triangles.\n\nInside each of these modules, we've got features with the same names being exported, and therefore each has the same export statement at the bottom\n\nWhen importing these into main.js, if we tried to use\n\nThe browser would throw an error such as \"SyntaxError: redeclaration of import name\" (Firefox).\n\nInstead we need to rename the imports so that they are unique\n\nNote that you could solve the problem in the module files instead, e.g.\n\nAnd it would work just the same. What style you use is up to you, however it arguably makes more sense to leave your module code alone, and make the changes in the imports. This especially makes sense when you are importing from third party modules that you don't have any control over.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
