An example of an AI chatbot conversation about common mistakes in JavaScript.
What are some common mistakes in JavaScript?
Some common mistakes in JavaScript include using '==' instead of '===' for comparisons, not declaring variables with 'let' or 'const', and forgetting to handle asynchronous code properly.
Can you explain why using '===' is better than '=='?
Using '===' checks for both value and type equality, preventing unexpected type coercion, while '==' only checks for value equality.
What about variable declarations? Why is it important?
Declaring variables with 'let' or 'const' helps avoid issues with hoisting and scope, leading to cleaner and more predictable code.
How can I handle asynchronous code properly?
You can use Promises, async/await syntax, or callbacks to manage asynchronous operations effectively.
