Using PsySH (GitHub) as the Yii shell

• Issue the following commands from the command line in your Yii application directory:
  • chmod +x shell
  • mkdir extensions/yiishell
  • wget -O extensions/yiishell/psysh psysh.org/psysh
  • chmod +x extensions/yiishell/psysh
• Copy the file init.php below to extensions/yiishell/init.php and update any paths to work with your application configuration
• Copy the file config.php below to extensions/yiishell/config.php. Change or add to the config array with the options you'd like to use (available options)
• Now you can start PsySH with the command extensions/yiishell/psysh extensions/yiishell/init.php --config extensions/yiishell/config.php

The goal here is to create an array of [0, 1, 2, 3, 4]. Every "Working ES6" column below accomplishes this. The first example fails to compile in TypeScript. The second example compiles and works, but throws errors in IE. The third example compiles, but does not achieve the desired functionality. The last example works as expected (it was found in the comments of Microsoft/TypeScript#8856).

Working ES6	TypeScript	Compiled JS	Result
[...Array(5).keys()]	error TS2461: Type 'IterableIterator' is not an array type.	n/a	n/a
Array.from(Array(5).keys())	Array.from(Array(5).keys())	Array.from(Array(5).keys())	[0, 1, 2, 3, 4], but does not work in IE
[...Array(5)].map((_, i) => i)	[...Array(5)].map((_: any, i: number) => i)	Array(5).slice().map(function (_, i) { return i; })	[undefined, undefined, undefined, undefined, undefined]
