JavaScript

Sample

• Prefer ES6 classes over prototypes.
• Use strict equality checks (=== and !==) except when comparing against (null or undefined).
• Prefer arrow functions =>, over the function keyword except when defining classes or methods.
• Use semicolons at the end of each statement.
• Prefer single quotes.
• Use PascalCase for classes, lowerCamelCase for variables and functions, SCREAMING_SNAKE_CASE for constants, _singleLeadingUnderscore for private variables and functions.
• Prefer template strings over string concatenation.
• Prefer promises over callbacks.
• Prefer array functions like map and forEach over for loops.
• Use const for declaring variables that will never be re-assigned, and let otherwise.
• Avoid var to declare variables.
