--description--

The parseInt() function parses a string and returns an integer. Here's an example:

js
const a = parseInt("007");

The above function converts the string 007 to the integer 7. If the first character in the string can't be converted into a number, then it returns NaN.

--instructions--

Use parseInt() in the convertToInteger function so it converts the input string str into an integer, and returns it.

--hints--

convertToInteger should use the parseInt() function

js
assert(/parseInt/g.test(__helpers.removeJSComments(code)));

convertToInteger("56") should return a number

js
assert(typeof convertToInteger('56') === 'number');

convertToInteger("56") should return 56

js
assert(convertToInteger('56') === 56);

convertToInteger("77") should return 77

js
assert(convertToInteger('77') === 77);

convertToInteger("JamesBond") should return NaN

js
assert.isNaN(convertToInteger('JamesBond'));

--seed--

--seed-contents--

js
function convertToInteger(str) {

}

convertToInteger("56");

--solutions--

js
function convertToInteger(str) {
  return parseInt(str);
}
