General Practices ​

Naming of Variable and Function ​

• Singular & Plural
• meaningful

let selectedCategoryId : number = 1;
let selectedCategoryIds : number[] = [1,2,3];
let isRedeemed : bool = true;

public function redeemStatus() : string
{
	return $is_redeemed ? "Redeemed" : "Open";
}

Be careful on Global & Magic ​

Be aware on API response changes ​

• as most of the frontend development language are strong type, changes of types or object key naming will cause error in frontend application.
