[JS] SIZE LIMITATION FROM STRING (FIT AND PROPER)

/**
    * @param {String} size
    * @param {Integer} max
**/

const overSize = (str, max) => {
    if(str.match('GB') || str.match('TB')) return data = { oversize: true }
    if(str.match('MB')) {
        let first = str.replace(/MB/g, '').trim()
        if(isNaN(first)) return data = { oversize: true }
        if(first > max) return data = { oversize: true }
            return data = { oversize: false }
    } else {
            return data = { oversize: false }
    }
}

// Example :
let size = '50.4 MB' // size
let v = overSize(size, 40) // max size is 40mb (fit and proper)
console.log(v) // { oversize: true }
