[JS] SIZE LIMITATION FROM STRING

/**
    * @param {String} size
    * @param {Array} ignore [2, 3, ..., 9] (from 2 until 9)
**/

const overSize = (str, ignore = []) => {
    if(str.match('GB') || str.match('TB')) return data = { oversize: true }
    if(str.match('MB')) {
        let first = (str.split('.')[0].replace(/MB/g, '')).trim()
        let max = ignore.some(v => first.startsWith(v))
        if(isNaN(first)) return data = { oversize: true }
        if(first.length > 1 && max) return data = { oversize: true }
        if(first.length > 2) return data = { oversize: true }
            return data = { oversize: false }
    } else {
            return data = { oversize: false }

}

// Example :
let size = '50 MB' // size
let v = overSize(size, [6, 7, 8, 9]) // max size less than 60mb and allow 59mb
console.log(v) // { oversize: false }
