What are the key differences between textContent and innerText in JavaScript?

textContent vs. innerText in JavaScript

Overview

textContent and innerText are two properties in JavaScript that return the text content of an element. However, there are subtle differences between the two.

Key Differences

• innerText:

  • Returns only visible text content.
  • Ignores hidden elements and whitespace.

• textContent:

  • Returns the teljes text content of an element, including hidden elements and whitespace.
  • More performance-heavy than innerText as it requires layout information.

Example

In your example:

var logo$ = document.getElementsByClassName('logo')[0];
logo$.textContent = "Example";

The above code will set the text content of the first element with the class "logo" to "Example". This includes any hidden elements or whitespace within that element.

Use Cases

• Use textContent if you need to retrieve the full content of an element, including hidden elements and whitespace.
• Use innerText if you need to retrieve only the visible text content of an element.
