JavaScript: Does an ES 6 module that is referenced by other modules have many instances in the RAM?
This video demonstrates the answers to the following questions.
File: test.html
****************
script src = "one.js" type = "module
File: one.js
*************
import * as foo from "./foo.js";
import * as two from "./two.js";
File: two.js
*************
import * as foo from "./foo.js";
File: foo.js
**************
export let cpuIntensiveOperation = function doSomethingCPUIntensive() { };
In a situation like the one above:
1. Does the module foo.js get loaded in the RAM more than once?
2. Does its code execute every time it is imported by another module?
3. In what sequence does the code of each of the modules execute?
