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 |
