Code Style of Alan-Liang

Variables

Always use var.

//good
var foo;
var bar="baz";

//bad
const foo="bar";
let bar="baz";

//terrible
foo="bar";

Strings

Always use double quotes.

//good
var str="some \"string\"";
var str2="some\n"+
         "long\n"+
         "long\n"+
         "string";

//bad
var str='string';
var str2=`string is ${str}`;
var str3=`some
long
string
`;

Functions

Always use normal function notion. Never use arrow functions or classes.

Why? For backward compatibility.

//good
function foo(bar){
	return bar;
};
var bar=function(baz){
	return baz;
};
baz(function(err,res){
	if(err)
		console.log(err.stack);
	else
		console.log(res);
});
function C(id){
	this.id=id;
};
C.prototype.setId=function(id){
	this.id=id;
	return this;
};
C.prototype.getId=function(){
	return this.id;
};

//bad
var foo=new Function("bar","return bar;");
var bar=baz=>baz;
baz((err,res)=>{
	//same as above
});
class C{
	constructor(id){
		this.id=id;
	}
	getId(){
		return this.id;
	}
	setId(id){
		this.id=id;
		return this;
	}
}

Indents

Use tab when coding on cell phone, and 2 spaces on computer.

Spaces

No space when unnecessary.

Why? no why.

//good
var foo=1;
function foo(a,b){}
var foo=function(a,b){};
if(foo>1){
	foo-=233;
}

//bad
var foo = 1;
function foo(a, b) {}
var foo = function (a, b) {};
if( foo > 1 ) {
	foo -= 233;
}

Naming

Always camelCaseLikeThis.

Modules

Always use CommonJS require()s.

//good
var foo=require("./foo");
module.exports=foo.bar.baz;

//bad
import {bar} from foo;
export default bar.baz;

Arrays

Always use fors.

var _arr=[1,2,3,4,5,6,7,8,9,10];
var arr=[];

//good
for(var i=0;i<_arr.length>i++){
	arr.push(_arr[i]+1);
}

//bad
_arr.forEach(function(el){
	arr.push(el+1);
});

Other

1. Use ;.
2. Use things as native as possible. (e.g. Do not use jQuery unless it is required.)
