Description

Suppose you have a file and you wish to import all of its contents into the current file. This can be done with the import * as syntax. Here's an example where the contents of a file named math_functions.js are imported into a file in the same directory:

import * as myMathModule from "./math_functions.js";

The above import statement will create an object called myMathModule. This is just a variable name, you can name it anything. The object will contain all of the exports from math_functions.js in it, so you can access the functions like you would any other object property. Here's how you can use the add and subtract functions that were imported:

myMathModule.add(2,3);
myMathModule.subtract(5,3);

Instructions

The code in this file requires the contents of the file: string_functions.js, that is in the same directory as the current file. Use the import * as syntax to import everything from the file into an object called stringFunctions.

Tests

tests:
  - text: Your code should properly use <code>import * as</code> syntax.
    testString: assert(code.match(/import\s*\*\s*as\s+stringFunctions\s+from\s*('|")\.\/string_functions\.js\1/g));

Challenge Seed

// Only change code above this line

stringFunctions.uppercaseString("hello");
stringFunctions.lowercaseString("WORLD!");

Solution

import * as stringFunctions from "./string_functions.js";

// add code above this line
stringFunctions.uppercaseString("hello");
stringFunctions.lowercaseString("WORLD!");
