interpolate into class property name js code example

Example 1: dynamic object property name javascript

let me = {
  name: 'samantha',
};

// 1. Dot notation
me.name; // samantha

// 2. Bracket notation (string key)
me['name']; // samantha

// 3. Bracket notation (variable key)
let key = 'name';
me[key]; // samantha

Example 2: nodejs how to use dynamic variable after dot

model.car // static way

const myDynamicVariable = 'car'
model[myDynamicVariable] // works like model.car - here you can dynamicly use a variable after dot
