js 给 最后一位数字自动+1

需求：version = '1.0.0' 或者 version = '1.0.0.GA'
要得到：1.0.1 或者 1.0.1.GA

function up (versionString) {
     let versionArray = versionString.split(".");
              for (let i = versionArray.length - 1; i >= 0; i--) {
                    let versionChar = versionArray[i];
                    if (!isNaN(versionChar)) {
                        versionArray[i] = versionChar.replace(/.$/, versionChar[versionChar.length - 1] - 0 + 1);
                        break;
                    }
                }
                return versionArray.join(".");
}

let version = up("1.0.0")
console.log(version)

version = up("1.0.10")
console.log(version)

version = up("1.0.10.SNAPSHOT")
console.log(version)

version = up("SNAPSHOT")
console.log(version)

version = up("1.2.kk.3")
console.log(version)

version = up(".kk.")
console.log(version)

version = up(".kk")
console.log(version)
