• Use meaningful names
• we use camelCase for variable names.
• All names start with a letter.
• Global variables will be written in UPPERCASE.
• Do not start names with a $ sign. It will put you in conflict with many JavaScript library names.

Example: sumOfTheMoney,
listOfBooks.

• Constant name will follow pascal case

Example: SomeVar

Method name should in camelCase.

Example:
let number = '23.32';
let result = parseInt(number);

console.log(result); // 23

Here, the parseInt() method of Number object is used to convert numeric string value to an integer value.

Class names should normally use the Pascal Casing method.
EXAMPLE:
class MyAge:
....x = 23

General rules for object definitions:

• Place the opening bracket on the same line as the object name.
• Use colon plus one space between each property and its value.
• Use quotes around string values, not around numeric values.
• Do not add a comma after the last property-value pair.
• Place the closing bracket on a new line, without leading spaces.
• Always end an object definition with a semicolon.
  
  Example:
  const person = {
  ..firstName: "John",
  ..lastName: "Doe",
  ..age: 50,
  ..eyeColor: "blue"
  };

Package or module name should in lower case. For multiple words use underscores between them.

All line should be less than 100 characters

Use 2 spaces per indentation level.
show(parameters,
..aligned,
..one,
..after,
..another)
{
// ...
}

General rules for simple statements:

Always end a simple statement with a semicolon.

Always put spaces around operators ( = + - * / ), and after commas:

Examples:
let x = y + z;
const myArray = ["Volvo", "Saab", "Fiat"];
