Can you explain type coercion with some examples?
Sure! Type coercion is when a value is converted from one type to another. For example, in JavaScript, if you add a number and a string, the number is coerced into a string.
Can you give me a specific example?
Absolutely! If you do 5 + '5'
, the number 5 is coerced into a string, resulting in '55'.
What about coercion with boolean values?
Good question! For instance, if you use if (0)
, the number 0 is coerced to false
, so the block won't execute.
Are there any pitfalls to be aware of?
Yes, type coercion can lead to unexpected results, like [] + 1
resulting in '1' instead of 1. It's important to be cautious!
