Javascript object result has additional character-CodePudding

This question might be ridiculous but I tried searching everywhere but I just can't find a good reference.

Why does some object in javascript has the structure like in the image attached below?

There is t character. And how do I convert the normal object to that form? For instance:

{
    key: "training",
    amount: 4500,
    currency: "PLN",
    label: "Training",
}

CodePudding user response：

The character t is the class name of the object that is passed as the value of the key value. As user @Vishnudev mentioned in the comments.

Consider the following code to recreate the JavaScript object and its structure in the image.

Code

class t{
  constructor( amount, currency, _sdkType) { 
    this.amount = amount
    this.currency = currency
    this._sdkType = _sdkType
  }
}
let value = new t(4500, "PLN", "Money")
let object = {
  value: value
}

console.log(object)

Output

Result as seen in the browser console.
