Storybook shows components in isolation and Vitest tests them automatically. We can see layout or behavior changes live. This makes testing simpler and more visual for frontend developers.

Good web design means keeping everything neat and easy to read by lining things up, leaving space between sections, using one or two fonts, and choosing colors that match the mood. Even if you are not great at design, using templates and clear layouts like having the logo in the top left and simple menus makes your site look clean and professional.

This made me think about how design itself is a kind of language. Colors, icons, and layouts communicate meaning even without words. In UX, every visual choice is part of this symbolic exchange between designer and user.

Designers use Hick’s Law to reduce cognitive load by limiting unnecessary options.

Design isn’t just looks, it’s how our brains react

It’s when people ignore facts that go against their views.Confirmation bias means we like to stick with what we already believe. We focus on information that makes us feel “right” and often ignore facts that might prove us wrong. For example, if you think your favorite team is the best, you’ll remember all their wins but forget their losses. This makes it harder to see the full picture and keeps us from learning new things. Leon Festinger first talked about this in 1957 when he explained how people try to avoid the stress of dealing with conflicting ideas.

Only Jobs could clap back so smoothly the guy thanked him after

Anchoring bias happens when people rely too much on the first piece of information they see. This first number or detail acts as a “reference point” for all later choices. For example, showing a high price first makes other options seem cheaper.

Priming means giving small hints or cues that affect how people think or act. It works by reminding them of something in their memory before they make a choice. For example, a friendly picture can make users feel more positive about an experience.

Hick’s Law shows more options slow decision making, so UX should stay simple. Priming demonstrates how prior cues influence user choices. Cognitive Load reminds us to minimize mental effort for smoother interactions.
