Is there a built-in function that can directly convert a string containing non-numeric characters to a number in JavaScript, without the need for using str.substring() followed by parseInt()?
For instance, how can I efficiently convert the string x1 to the number 1.
Although it does not involve a single native function, here is a straightforward method for extracting positive integers from a string:
let number = +str.match(/\d+/);
If you need to consider the presence of a dot and a sign in the string, you can use this alternative approach:
let number = +str.match(/-?\d+(?:\.\d*)?/);
Keep in mind that if there are no digits in the string, this will result in 0.
