前端工程師面試問題集

@版本 2.0.0

譯注：此翻譯版，主要給不能流利的讀英文的人看，相關專有名詞還是保留原文。翻譯不好地方請協助pull request.

此repository包含了一些前端開發的面試問題，來審查一個有潛力的面試者。這並不是建議你對同一個面試者問上所有的問 (那會花費好幾小時)。從列表中挑幾個題目，應該就夠幫助你審查面試者是否擁有你需要的技能。

Rebecca Murphey 的 Baseline For Front-End Developers 也是一篇很棒且值得讀的文章在你開始面試之前。

"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
To create the SSH keys, type ssh-keygen -t rsa -C "[email protected]". Th

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	package main

	import (
	"code.google.com/p/go-tour/pic"
	"image"
	"image/color"
	)


	type Image struct{

	Function::property = (prop, desc) ->
	Object.defineProperty @prototype, prop, desc

	class Person
	constructor: (@firstName, @lastName) ->
	@property 'fullName',
	get: -> "#{@firstName} #{@lastName}"
	set: (name) -> [@firstName, @lastName] = name.split ' '

	p = new Person 'Leroy', 'Jenkins'

	When to use it?
	----------------
	A consistent frame-rate can be better than a janky experience only
	occasionally hitting 60fps. Use this trick to target a specific frame-
	rate (e.g 30fps, 48fps) until browsers better tackle this problem

	Exercise: Loops and Functions

	As a simple way to play with functions and loops, implement the square root function using Newton's method.

	In this case, Newton's method is to approximate Sqrt(x) by picking a starting point z and then repeating: z - (zz - x) / (2 z)
