What are some examples of coercion in programming?
Coercion in programming refers to the automatic conversion of values 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 in JavaScript?
Sure! If you write 5 + '5'
, JavaScript converts the number 5 to a string, resulting in '55'.
What about coercion in Python?
In Python, coercion is less common. However, if you use str(5)
, it converts the integer 5 to the string '5'.
Are there any issues that can arise from coercion?
Yes, coercion can lead to unexpected results, such as 0 == '0'
being true, but 0 === '0'
being false in JavaScript due to type strictness.
