Welcome to The Refactoring Tales, a book that documents some of the refactorings and changes I’ve made in recent (and mostly real-life) projects. This book isn’t going to teach you about language constructs, conditionals, functions, or so on, but hopefully offer insight into how to take steps to make your code more readable and more importantly, maintainable.

Example 1: Append an array to another array.

5
var arr1 = [1, 2, 3];
var arr2 = [4, 5, 6];
Array.prototype.push.apply(arr1, arr2);
console.log(arr1); // [1, 2, 3, 4, 5, 6]

Example 2: Get the max/min item in an array of numbers.

1
2
3
var numbers = [12, 1, 35, 98, 34, 100];
var max = Math.max.apply(Math, numbers);
var min = Math.min.apply(Math, numbers);

Grunt has two methods for importing external data:

  • grunt.file.readJSON
  • grunt.file.readYAML

For example, you can load data from a file into configuration of GruntFile:

1
2
3
4
5
6
7
8
9
10
11
12
module.exports = function (grunt) {
    
    grunt.config.init({
        colors: grunt.file.readJSON('colors.json'),
        white: '<%= colors.white %>',
        green; '<%= colors.green %>'
    });
    grunt.registerTask('default', function () {
        grunt.log.writeln(grunt.config.get('green'));
    });
});

Using Tempalte to store external data into specific config properties, such as white and green in the above example. Then, you can get the data by method grunt.config.get().

Users of Git are hopefully aware that a git pull does a git fetch to pull down data from the specified remote, and then calls git merge to join the changes received with your current branch’s work. However, that may not always be the best case. You can also rebase the changes in, and that may end up being a lot cleaner. This can be done simply by tacking on the --rebase option when you pull, like so:

1
git pull --rebase <remote name> <branch name>
