Js programming habits improved by 1

1. During js programming, a space is left before and after keywords and parentheses to improve program readability.

 

Function x () {...}. After JavaScript code is compressed, spaces are removed, mainly to improve readability.

 

2. When multiple variables are declared at the same time, try to use a var keyword separated by commas, so that JavaScript code compression can be more efficient.

 

Var x = 1,

 

Y = 2,

 

Z;

 

The code is readable and compressed to remove unnecessary blank lines and spaces.

 

In this case:

 

Var x = 1;

 

Var y = 2;

 

Var z;

 

All three var values are retained after compression.
