When is Vanilla JavaScript a Better Choice Than jQuery?

Comparing Vanilla JavaScript and jQuery: When Plain JavaScript Is Preferred

jQuery, a popular JavaScript library, has been widely used for its simplified syntax and simplified DOM manipulation. However, certain scenarios favor the use of plain JavaScript due to its performance advantages and compactness.

Instances Where Vanilla JavaScript Excels Over jQuery

Direct Attribute Access

Instead of jQuery's $(this).attr("id"), plain JavaScript offers this.id for direct attribute access.

Native DOM Methods

This.value, this.className, this.selectedIndex, this.options, and other native DOM methods provide faster and more precise access to specific properties.

Element Traversals

This.parentNode, this.rows, this.cells, and other methods navigate the DOM structure directly, yielding performance benefits.

Boolean Properties

Plain JavaScript enables direct access to boolean properties like this.checked, this.selected, this.disabled, and this.readOnly.

Element Properties

This.href, this.hostname, this.pathname, and this.search provide direct access to element properties in HTML tags like <a> and <img>.

Advantage of Plain JavaScript

Performance: Direct access to DOM elements through plain JavaScript often results in faster execution than using jQuery.

Code Reduction: In certain scenarios, plain JavaScript allows for more concise and readable code, as it eliminates the overhead associated with the jQuery syntax.

Performance in Loops: For operations performed repeatedly in loops, plain JavaScript may yield superior performance due to its direct manipulation of the DOM.

Conclusion

While jQuery offers convenience and simplicity, plain JavaScript provides performance and compactness advantages in specific situations. Choosing the right approach depends on the performance requirements, code readability, and specific DOM manipulation needs of the application.
