An example of an AI chatbot conversation about finding string length in JavaScript.
How do I find the length of a string in JavaScript?
You can use the .length property of a string. For example, let str = 'Hello'; console.log(str.length); will output 5.
Can I use this method for strings with spaces?
Yes, the .length property counts all characters, including spaces. For example, 'Hello World'.length will return 11.
What about empty strings?
An empty string has a length of 0. For example, let emptyStr = ''; console.log(emptyStr.length); will output 0.
Is there a way to count specific characters in a string?
Yes, you can use a loop or the .split() method to count specific characters. For example, to count 'o' in 'Hello World', you can do: let count = str.split('o').length - 1;.
