Yes, I promise I've read the Contributions Guidelines (please feel free to remove this line).

Specifically quoting these guidelines regarding typos:

Typos?

Please don't worry about minor text typos. These will almost certainly be caught during the editing process.

If you're going to submit a PR for typo fixes, please be measured in doing so by collecting several small changes into a single PR (in separate commits). Or, just don't even worry about them for now, because we'll get to them later. I promise.

example code

The example code will cause a SyntaxError: Unexpected token '.' by record.name.

function getStudents(data) {
    var studentRecords = [];

    for (let record of data.records) {
        let id = `student-${ record.id }`;
        studentRecords.push({
            id,
            record.name  // <---- SyntaxError: Unexpected token '.', fixed this line to `name: record.name`
        });
    }

    return studentRecords;
}
             record.name
