How to extract the value from the object of arrays in js?-CodePudding

I need help to extract the codes from a pdf file that has been converted into a json object. Is it possible to create new array with only fs codes like this FS0003918245, FS0003940457, FS0003898043. From the existing one make a new one with fs codes only. thank you

let array = ["FS0003918245", "FS0003940457", "FS0003898043"]

let array = [

CodePudding user response：

You can simply use this code:

const regex = /FS\d{10}/g
const result = array.map(innerArray => {
    return innerArray.filter(f => regex.test(f)).map(m=>{
        return m.match(regex)
    })
}).flat(Infinity)

Or this one what do the same:

const regex = /FS\d{10}/g
const result = array.map(innerArray => {
    return innerArray.map(m => {
        return m?.match(regex)
    })
}).flat(Infinity).filter(Boolean)

Or to avoid duplicates you can also add:

const resultWithoutDuplicates = [...new Set(result)]

I will give you a rodumentary solution, feel free to improve it I have not touch JS in years
