Presentation

DataFrame-js provides an immutable data structure for javascript and datascience, the DataFrame, which allows to work on rows and columns with a sql and functional programming inspired api.

With the DataFrame, you can easily do a ton of complex stuff such as join, groupby, exploration tasks, machine learning...

It's mainly designed to work on server-side (with node) but it also works in the browser (without file system related features).

Example:

import DataFrame from "dataframe-js";
import { data, columns } from "./titanic_data.js";
const df = new DataFrame(data, columns);
const filteredDf = df
    .filter(row => row.get("survived") === "yes")
    .select("class", "age", "sex");
filteredDf.show(3);

| class       | age        | sex        |
----------------------------------------
| 1st class   | adults     | man        |
| 1st class   | adults     | man        |
| 1st class   | adults     | woman      |
