How to implement color gradient effect in JavaScript

Quick answer：

To implement a color gradient effect in JavaScript, you can use CSS gradients and manipulate them with JavaScript. You can define the gradient in CSS and then use JavaScript to change the gradient's direction, color stops, or other properties dynamically. For example, you can use the 'linearGradient' and 'radialGradient' functions in CSS and manipulate them using JavaScript methods like 'querySelector', 'style', and 'addEventListener'.
