where'd range comes from?

[rimzzlabs]

Hello, Im just curious about what is happening here

react-datepicker/docs-site/src/examples/renderCustomHeader.js

Line 3 in df2ac5c

const years = range(1990, getYear(new Date()) + 1, 1);

where did the range function comes from?

I would also like to know where the range function is imported from.
