The main problem is that when a string is capitalized in JavaScript, it is not always treated as a word. For example, “JavaScript” is not treated as a word, but “Java” is. This can cause problems when you are trying to do things like search for words in a string.
var str = "javascript capitalize string";
var res = str.replace(/wS*/g, function(txt){return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();});
This code is written in JavaScript. It defines a function that capitalizes the first letter of each word in a string. The function takes a string as an input and outputs a new string with the first letter of each word capitalized.
String tips
There are a few tips that can help you when working with strings in JavaScript.
First, remember that strings are immutable. This means that once you create a string, you cannot change its contents. This is useful when you want to ensure that a string is always consistent across different executions of your code.
Second, keep in mind the difference between regular expressions and string literals. A regular expression is a special type of string that can be used to match patterns in text. String literals, on the other hand, are simply strings that contain no special characters and can be used anywhere in your code. When working with regular expressions, it is important to use the correct escape sequences (e.g., d for a digit character). For more information on regular expressions, see the Mozilla Developer Network article on RegExp: http://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/RegExp/.
Finally, it is important to note that JavaScript strings are case-sensitive. This means that the letters A through Z are treated differently than the letter z.
String Methods
There are a few methods that can be used with strings in JavaScript. The first is to create a new string by concatenating two or more strings together. The second is to search for a string within another string. The third is to replace a substring within a string. The fourth is to split a string into an array of strings based on certain criteria.
