| 587d7b8d367417b2b2512b59 | Import a Default Export | 1 |
Description
export default and its uses. It is important to note that, to import a default export, you need to use a different import syntax.
In the following example, we have a function, add, that is the default export of a file, "math_functions". Here is how to import it:
import add from "math_functions";The syntax differs in one key place - the imported value,
add(5,4); //Will return 9
add, is not surrounded by curly braces, {}. Unlike exported values, the primary method of importing a default export is to simply write the value's name after import.
Instructions
subtract, from the file "math_functions", found in the same directory as this file.
Tests
tests:
- text: Properly imports <code>export default</code> method.
testString: 'getUserInput => assert(getUserInput("index").match(/import\s+subtract\s+from\s+"math_functions"/g), "Properly imports <code>export default</code> method.");'
Challenge Seed
"use strict";
subtract(7,4);
Before Test
window.require = function(str) {
if (str === 'math_functions') {
return function(a, b) {
return a - b;
}}};
