--description--

Number is a data type in JavaScript which represents numeric data.

Now let's try to add two numbers using JavaScript.

JavaScript uses the + symbol as an addition operator when placed between two numbers.

Example:

const myVar = 5 + 10;

myVar now has the value 15.

--instructions--

Change the 0 so that sum will equal 20.

--hints--

sum should equal 20.

assert(sum === 20);

You should use the + operator.

assert(/\+/.test(__helpers.removeJSComments(code)));

--seed--

--after-user-code--

(function(z){return 'sum = '+z;})(sum);

--seed-contents--

const sum = 10 + 0;

--solutions--

const sum = 10 + 10;
