How do you convert a string to an integer in JavaScript?
a) parseInt()
b) parseFloat()
c) Number()
d) toString()
Answer:
a) parseInt()
Explanation:
The parseInt() function converts a string to an integer by parsing the string and returning the first integer value found. If the string does not contain a number, NaN (Not-a-Number) is returned.
Example:
let num = parseInt("123");
console.log(num); // Output: 123
