Git provides multiple commands for listing branches. All commands use the function of git branch, which will provide a list of a certain branches, depending on which options are put on the command line. Git will if possible, indicate the currently selected branch with a star next to it. GoalCommand...

A replacer function can be used to filter or transform values being serialized. const userRecords = [ {name: "Joe", points: 14.9, level: 31.5}, {name: "Jane", points: 35.5, level: 74.4}, {name: "Jacob", points: 18.5, level: 41.2}, {name: "Jessie",...

A reviver function can be used to filter or transform the value being parsed. 5.1 var jsonString = '[{"name":"John","score":51},{"name":"Jack","score":17}]'; var data = JSON.parse(jsonString, function reviver(key, value) { return ke...

JavaScript has two primary ways to represent binary data in the browser. ArrayBuffers/TypedArrays contain mutable (though still fixed-length) binary data which you can directly manipulate. Blobs contain immutable binary data which can only be accessed through the asynchronous File interface. Conver...

DataViews provide methods to read and write individual values from an ArrayBuffer, instead of viewing the entire thing as an array of a single type. Here we set two bytes individually then interpret them together as a 16-bit unsigned integer, first big-endian then little-endian. var buffer = new Ar...

var data = 'iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACN' + 'byblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHx' + 'gljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=='; var characters = atob(data); var array = new Uint8Array(characters.length); for (var i = 0; i < characters.length; i++) { array[i] ...

Template literals are a special type of string literal that can be used instead of the standard '...' or "...". They are declared by quoting the string with backticks instead of the standard single or double quotes: `...`. Template literals can contain line breaks and arbitrary expression...

The idea of bound and unbound methods was removed in Python 3. In Python 3 when you declare a method within a class, you are using a def keyword, thus creating a function object. This is a regular function, and the surrounding class works as its namespace. In the following example we declare method ...

#! /bin/bash for i in {1..10}; do # {1..10} expands to "1 2 3 4 5 6 7 8 9 10" echo $i done This outputs the following: 1 2 3 4 5 6 7 8 8 10

In the same module Inside a module named "MyModule", Xcode generates a header named MyModule-Swift.h which exposes public Swift classes to Objective-C. Import this header in order to use the Swift classes: // MySwiftClass.swift in MyApp import Foundation // The class must be `public`...

If MyFramework contains Objective-C classes in its public headers (and the umbrella header), then import MyFramework is all that's necessary to use them from Swift. Bridging headers A bridging header makes additional Objective-C and C declarations visible to Swift code. When adding project files, ...

Supplying pow() with 3 arguments pow(a, b, c) evaluates the modular exponentiation ab mod c: pow(3, 4, 17) # 13 # equivalent unoptimized expression: 3 ** 4 % 17 # 13 # steps: 3 ** 4 # 81 81 % 17 # 13 For built-in types using modular exponentiation is only possible...

You have up to 5 sources for git configuration: 6 files: %ALLUSERSPROFILE%\Git\Config (Windows only) (system) <git>/etc/gitconfig, with <git> being the git installation path. (on Windows, it is <git>\mingw64\etc\gitconfig) (system) $XDG_CONFIG_HOME/git/config (Linux/Mac on...

Using the strtotime() function combined with date() you can parse different English text descriptions to dates: // Gets the current date echo date("m/d/Y", strtotime("now")), "\n"; // prints the current date echo date("m/d/Y", strtotime("10 September 2...

A Swift String is made of Unicode code points. It can be decomposed and encoded in several different ways. let str = "ที่👌①!" Decomposing Strings A string's characters are Unicode extended grapheme clusters: Array(str.characters) // ["ที่", "👌", "①", ...

git rev-list --oneline master ^origin/master Git rev-list will list commits in one branch that are not in another branch. It is a great tool when you're trying to figure out if code has been merged into a branch or not. Using the --oneline option will display the title of each commit. The ^ ...

Functions can take parameters so that their functionality can be modified. Parameters are given as a comma separated list with their types and names defined. func magicNumber(number1: Int) { print("\(number1) Is the magic number") } Note: The \(number1) syntax is basic String I...
