npm install @syransong/lotide

Require it:

const _ = require('@syransong/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]

• findKey: A function that goes through an object and returns the first key for which the callback returns a 'truthy' value
• findKeybyValue: A function that goes through an object and searches for the key where its value matches a given value
• head: A function that returns the value of the zeroth index in an array
• letterPositions: A function that returns all the indices where a certain letter occurs in a string
