var gulp = require('gulp'),
    uglify = require('gulp-uglify');

gulp.task('scripts', function() {
    gulp.src('js/*.js')
        .pipe(uglify())
        .pipe(gulp.dest('build/js'));
});

// Styles Task
// Uglifies
gulp.task('styles', function() {
    console.log('Runs Style');
});

// Watch files
gulp.task('watch', function() {
    gulp.watch('js/*.js', ['scripts'])
});

gulp.task('default', ['scripts','styles']);
