Working codepen: http://codepen.io/leongaban/pen/oxwLzE?editors=1010The function below takes in user entered text through the cli: V=patch gulp buildIt then checks for the last version of the build folder, then iterates the appropriate version number.Hoping to condense all the if/else into more functional code.lastVersion starts as an empty string var lastVersion = '';The ver value that is passed into this function from the user will be 1 of these commands:V=major gulp buildV=minor gulp buildV=patch gulp buildSo ver will be major, minor or patch...function generateNextVersion(ver) {    var major, minor, patch;    var versionArray = lastVersion.split('.');    major = parseInt(versionArray[0]);    minor = parseInt(versionArray[1]);    patch = parseInt(versionArray[2]);    if (ver === 'major') {        major = parseInt(versionArray[0]) + 1;    }    else if (ver === 'minor') {        minor = parseInt(versionArray[1]) + 1;    }    else if (ver === 'patch') {        patch = parseInt(versionArray[2]) + 1;    }    version = major + '.' + minor + '.' + patch;    if (ver === '' || ver === undefined) {        version = '0.0.0';    }    gutil.log(gutil.colors.blue.bold('##################################################'));    gutil.log(gutil.colors.blue.bold('         Building Dashboard version '+version));    gutil.log(gutil.colors.green.bold('~~           All change is detectable           ~~'));    gutil.log(gutil.colors.blue.bold('##################################################'));}
Gulp task to increment a major, minor, or patch level of the version number of the last build

The first thing that I see is that:    major = parseInt(versionArray[0]) + 1;Is a bit redundant. You already say:major = parseInt(versionArray[0]);Just do:major += 1;(This is similar for all the major, minor and patch statements)You can also use a switch-case instead of if statements so instead of:if (ver === 'major') {    major = parseInt(versionArray[0]) + 1;}else if (ver === 'minor') {    minor = parseInt(versionArray[1]) + 1;}else if (ver === 'patch') {    patch = parseInt(versionArray[2]) + 1;}You have:switch (ver) {    case 'major':        major += 1;        break;    case 'minor':        minor += 1;        break;    case 'patch':        patch += 1;        break;}
