What are some common type conversion errors in JavaScript?
Common type conversion errors in JavaScript include issues like adding a number to a string, which can lead to unexpected results.
Can you give me an example of that?
Sure! If you do 5 + '5'
, it will result in '55'
instead of 10
because the number is converted to a string.
What about converting booleans?
When converting booleans, true
becomes 1
and false
becomes 0
. For example, Number(true)
returns 1
.
How can I avoid these errors?
To avoid these errors, always use explicit type conversion methods like Number()
, String()
, or Boolean()
.
