What are some examples of type conversion in JavaScript?
In JavaScript, type conversion is the process of converting a value from one type to another. For example, when you use the +
operator with a number and a string, JavaScript converts the number to a string.
Can you give me a specific example?
Sure! If you do 5 + '5'
, JavaScript converts the number 5 to a string, resulting in '55'.
What about converting a string to a number?
You can use the Number()
function or the unary +
operator. For example, Number('10')
or +'10'
both convert the string '10' to the number 10.
Are there any automatic conversions that happen?
Yes, JavaScript performs automatic type conversion in certain situations, like when using comparison operators. For example, 5 == '5'
returns true because the string is converted to a number.
