Cespu asked me about a mini software, to test migrants italian capability.

He needs to count how many words are used from a pre-defined dictionary.

I’ve implemented something like this:

let tokens = [
    'cane',
    'gatto',
    'pizza',
    'strada',
]

let text = `sono andato a mangiare una pizza, ma per strada ho schiacciato un
gatto che mi ha tagliato la strada.`

let words = text.split(/[ .,!?,;,...]/g)

let result = words.reduce( (acc, curr) => {
    // console.log(curr)
    if ( tokens.includes(curr) ) {
        if ( Object.keys(acc).includes(curr) ){
            acc[curr] += 1
        } else {
            acc[curr] = 1 
        }
    }
    return acc
}, {})

console.log(result)

to launch it, just run:

node test.js
