Map Functions

Mapping is about transforming data from one value to another.

1. Use the number to words module and map, to transform this

array of number to array of words

const converter = require('number-to-words')

// converter.toWords(10)  // ten
const numbers = [1,2,3,4,5,6,7,8,9,10,20,30,99, -2]

2. Use the map function to add 10 to array of numbers


const numbers = [1,2,3,4,5,6,7,8,9,10,20,30,99, -2]

3. Use the map function and hyperscript to tranform a list of strings to

an unordered list

hyperscript docs

const h = require('hyperscript')

const buzzwords = require('buzzwords')
const li = (w) => h('li', w)
console.log(h('ul', __ ))

4. Use the map function to convert a list of colors to their rgb code.

const convert = require('color-convert')
const cssColorList = require('css-color-list')

// ex: convert.keyword.rgb('red')

5. Use the map function transform a list of movies objects from a movie

db search into a list of movie posters.

const h = require('hyperscript')


const request = require('request')
const search = (query, callback) => {
  request({
    method: 'GET',
    json: true,
    url: 'http://www.omdbapi.com/?r=json&s=' + query
  }, (e,r,b) => callback(e,b))
}
const img = (url) => h('img', {src: url})
search('batman', (e,b) => {
  // map over results and show movie posters
})
