Can I use the propertie .lenght to count numbers in a string?

Can I use the propertie .lenght to count numbers in a string? ( console.log(’ 3+4’ . lenght);

You can, but you are probably running into an error because of the spelling. length is the correct one

thank very much, details are very important in coding. :blush:

Welcome to the forums!

.length is a property that will tell you how many characters there are in a string, not only how many numbers there are.

Example

console.log("3 + 4".length); // prints 5

In the above example, 5 is printed because there are five characters in the string: 3, space, +, another space, and 4.


Let’s say you wanted to count the number of occurrences of numerical digits in a string. How could you go about doing that?
