functionfoundry

FunctionFoundry is a JavaScript library with an interface similar to the classic spreadsheet functions.

The code runs in Node.js and browsers. The library provides ~100 functions but it is small (~30kb minified).

For more information see the docs or read the annotated code.

quickstart

npm install --save functionfoundry

var { and, eq, len, gt, lt, isnumber, isText, isEmail, isEmpty, lower, proper, text, date} = require('functionfoundry')
// print `true`
console.log(
  and(
    isnumber(1),
    isText('this is'),
    isEmail('[e-mail]'),
    isEmpty(''),
    gt(2, 1),
    lt(1, 2),
    eq(len('foo'), 3),
    eq(lower('HAPPY'), 'happy'),
    eq(proper('happy'), 'Happy'),
    eq(text(4200.00, "$#,###.00"), '$4,200.00'),
    eq(text(date(2000, 2, 1), "m-d-yyyy"), '2-1-2000')
  )
)
