Want to practice for your next interview?

Then use this prompt and ask Chat GPT to act as an interviewer πŸ˜„πŸ‘‡ (Tap to copy)

I want you to act as an interviewer. I will be the
candidate and you will ask me the
interview questions for the position position. I
want you to only reply as the interviewer.
Do not write all the conservation at once. I
want you to only do the interview with me.
Ask me the questions and wait for my answers.
Do not write explanations. Ask me the
questions one by one like an interviewer does
and wait for my answers. My first
sentence is "Hi"

Now see how it goes. All the best for your preparation

Common Coding Mistakes to Avoid
Even experienced programmers make mistakes.


Undefined variables:

Ensure all variables are declared and initialized before use.

Type coercion:

Be mindful of JavaScript's automatic type conversion, which can lead to unexpected results.

Incorrect scope:

Understand the difference between global and local scope to avoid unintended variable access.

Logical errors:

Carefully review your code for logical inconsistencies that might lead to incorrect output.

Off-by-one errors:

Pay attention to array indices and loop conditions to prevent errors in indexing and iteration.

Infinite loops:

Avoid creating loops that never terminate due to incorrect conditions or missing exit points.

Example:
// Undefined variable error
let result = x + 5; // Assuming x is not declared

// Type coercion error
let age = "30";
let isAdult = age >= 18; // Age will be converted to a number

By being aware of these common pitfalls, you can write more robust and error-free code.
