Answer
Using '=' for comparison instead of '=='. Frame the concept in practical terms so you can explain it during interview discussion.
Beginners often confuse '=' (assignment) with '==' (comparison). In an e-commerce scenario, if you're checking if a product's stock is zero, use 'if (stock == 0)' instead of 'if (stock = 0)'. The latter assigns zero to 'stock', causing logical errors. Always double-check the context when using these operators.
