Assign a string but get back an object -the browser at play?

Given this tag:

<p id="myp">foo para

I know you're not supposed to, but if I assign a string to the style property of the corresponding DOM object, I can change its style:

let p = document.getElementById('myp');
p.style = 'color: red'; //assign a string

p.style should now point to a string, I suppose. But if I then ask for the style property, I get an object rather than a string:

console.log(p.style); //get back an object

Normally in JavaScript if I assign a string to a variable or object property, I expect the value to still be a string when I ask for that value. So is the browser jumping in to change this, or is there a JavaScript mechanism at play?

document.getElementById returns an HTMLElement, and if you look at it's prototype

we see that style is not a "normal" property, but actually a getter and setter.

Obviously this is a super simplified example, but essentially it would be implemented something like:

  let element = {
        color: 'red',
        get style() {
            return { color: this.color }
        },
        set style(s) {
            this.color = s.split(': ')[1]
        }
    }

element.style = 'color: blue';
console.log(element.style);

(2) substring Copies the portion of str that begins at the character position subpos and spans sublen characters (or until the end of str, if either str is too short or if sublen is string::npos).

If you debug HTMLElement.prototype in the console, you can see that style is an accessor property. When you assign a value to it, instead of just overwriting the property in question it executes a setter method, which can override the value you passed. This is without a doubt in place to ensure that the style property is always an object (namely an instance of CSSStyleDeclaration), since a lot of things rely on that.

To overwrite the style attribute of the element, you can safely use p.setAttribute('style', 'color: red');

A lot of people are learning JavaScript to become front-end and/or back-end developers. History JavaScript is an Object Based programming language that allows creation of interactive web pages.

Style of the p element is an object containing all of its styles, you need to select which style you want.

UPDATE: You can get your string back from the cssText also in the snippet.

p.style = 'color: red'; I believe this line is taken as:

p.style.color: 'red'; 

let p = document.getElementById('myp');
p.style = 'color: red';
console.log(p.style.color);

console.log(p.style.cssText);
<p id="myp">foo para<p>

According to mozilla documentation

The HTMLElement.style property is used to get as well as set the inline style of an element. While getting, it returns a CSSStyleDeclaration object that contains a list of all styles properties for that element with values assigned for the attributes that are defined in the element's inline style attribute.
