var propose = require('propose');
var dictionary = ['hello', 'world'];
var word = 'hallo';
propose(word, dictionary); //hello

var propose = require('propose');
var dictionary = ['aaaaaaaa', 'baabbbb', 'ccccc'];
var word = 'ab';
propose(word, dictionary, {
    threshold: 0.5
}); // null as the most similar word does not meet the threshold value

ignoreCase true, false specifies whether ignore case when comparing two words

var propose = require('propose');
var dictionary = ['HELLO', 'hallo'];
var word = 'hello';
propose(word, dictionary, {
