Project Experience:
- A few diverse projects in your portfolio are sufficient; the diversity and challenges tackled in the projects are more important than their size or quantity.
- Big projects aren't a must for entry-level roles.
Technical Skills You Don’t Need to Master:
- Setting up complex React apps, deployment pipelines, or using advanced libraries like Redux or Tailwind is not expected for juniors.
- Many advanced setups differ across companies and are often not your responsibility initially.
Problem-Solving Approach:
- It's normal to use resources like Google, Stack Overflow, or ChatGPT during development. Finding answers online is a common practice among developers.
Essential JavaScript Skills:
- Master JavaScript basics like constants, functions, the spread operator, promises, and object/array manipulations.
