There are two different methods for using objects in programming. I am curious to understand if the difference lies in the syntax or if there is more to it.
Method 1
body(data) = {
item1: data.val1;
item2: data.val2;
item3: data.val3;
}
Method 2
body(data) = {
item1 = data.val1,
item2 = data.val2,
item3 = data.val3
}
body.item1 = '';
body['item2'] = '';
When looking at your scenario, there may not seem to be a distinction, but utilizing the array-like syntax can prove beneficial when incorporating a variable as the object property, like so:
const data={}
const key = 'value';
data[key] = 'a great result'
alert(data.value) //This alert should display "a great result"
When it comes to accessing properties on Objects, there is actually no significant difference between using the dot notation or the square brackets notation. However, following coding standards, it is recommended to use the dot notation for referencing properties. The only scenario where the square brackets notation is preferred is when you need to access a property dynamically at runtime using a variable.
