The main gotcha in this notation is IE. Never ever leave a trailing comma before the closing curly brace or you'll be in trouble.var moviesthatneedbetterwriters = new Array (' Transformers ', '
code as follows:

A more concise formulation is:
Copy Code code as follows:

];
For arrays, there is an associative array of such a special
1. Simplify code
JavaScript defines objects and arrays very simply, and we want to create an object that is generally written like this:
Copy Code code as follows:
Car.colour = ' red ';
Car.wheels = 4;
Car.hubcaps = ' spinning ';
Car.age = 4;
The following writing can achieve the same effect:
Copy Code code as follows:
Colour: ' Red ',
Wheels:4,
Hubcaps: ' Spinning ',
Age:4
}
The writing is much shorter, and you don't have to repeat t
JavaScript is a very popular programming language, many developers will choose JavaScript as an introductory language, this article to share JavaScript seven practical skills, best practices, and other very useful content. In the past, if you want to create an object, you need to do this:
var car = new Object ();
Car.colour = ' red ';
Car.wheels =;
Car.hubcaps = ' spinning ';
Car.age =; The following writing can achieve the same effect: var car = {
colour: ' Red ',
wheels:,
hubcaps: ' S
concise way of writing the array, which we have declared in the past:
1
var moviesthatneedbetterwriters = new Array (
2
' Transformers ', ' Transformers2 ', ' Avatar ', ' Indiana Jones 4 '
3
);
more concise writing is:
1
var moviesthatneedbetterwriters = [
2
' Transformers ', ' Transformers2 ', ' Avatar ', '
as follows:
Var moviesThatNeedBetterWriters = new Array ('Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4');
A more concise statement is as follows:
The Code is as follows:
Var moviesThatNeedBetterWriters = ['Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4'];
For arrays, there is also a special thing like associating arrays. You will find that many codes define objects as foll
after braces; otherwise, errors may occur in IE.
In addition, there is a simple way to write arrays. In the past, we declared arrays as follows:
1 varMoviesThatNeedBetterWriters =NewArray (2Transformers,Transformers2,Avatar,Indiana Jones 43 );
A more concise statement is as follows:
1 varMoviesThatNeedBetterWriters = [2Transformers,Transformers2,Avatar,Indiana Jones 43];
For arrays, there is also a special
= new Array ('Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4');
Use the simple statement:
The Code is as follows:
Var moviesThatNeedBetterWriters = ['Transformers ', 'transformers2', 'Avatar', 'Indiana Jones 4'];
Another question about arrays is whether there is an associated array. You will find a lot of code examples to define examples like this on the car
