The indent level recommends 4 space characters as an indent level. It is recommended not to omit semicolons at the end of a statement. The length of the line should be no more than 80 characters long. NewLine wraps after the operator, and the next line adds two levels of indentation. Exception: When assigning a value to a variable, the position of the second row is aligned with the position of the assignment operator. For example:
var result = something + anotherThing + yetAnotherThing + somethingElse + anotherSomethingElse;A blank line is named between a method's local variable and the first statement in a method before a multiple-line or single-line comment is a camel case: starts with a lowercase letter, Capitalize the first letter of each subsequent word.

Multi-line string notation: Use a string connector (+) to tell a string into multiple copies. //Good var longString = "Here‘s the story of a man " + "named Brady.";   //这是一种奇技淫巧而非语言特性。在Google的JavaScript风格指南中是禁止的。 var longString = "Here‘s the story of a man \ named Brady.";Numbers do not omit parts before or after the decimal point. Don't write octal.        Null is used to initialize a variable and may be assigned to an object.        Used to compare to an already initialized variable, which can or might not be an object.        Used as a parameter when the function's parameters are expected to be an object. When the return value of a function is expected to be an object, the return value is used as outgoing.        The following scenario does not use NULL to not use NULL to detect whether a parameter was passed in. Do not use NULL to detect an uninitialized variable. Undefined avoid using undefined, you can effectively ensure that typeof returns "undefined" only in one case.
