## Description
|
||
|
|
<section id='description'>
|
||
|
|
In the last challenge, you learned about <code>export default</code> and its uses. It is important to note that, to import a default export, you need to use a different <code>import</code> syntax.
|
||
|
|
In the following example, we have a function, <code>add</code>, that is the default export of a file, <code>"math_functions"</code>. Here is how to import it:
|
||
|
|
<blockquote>import add from "math_functions";<br>add(5,4); //Will return 9</blockquote>
|
||
|
|
The syntax differs in one key place - the imported value, <code>add</code>, is not surrounded by curly braces, <code>{}</code>. Unlike exported values, the primary method of importing a default export is to simply write the value's name after <code>import</code>.
