To get the first letter of each word in a string: Call the split() method on the string to get an array containing the words in the string. Call the map() method to iterate over the array and return the first letter of each word. Join the array of first letters into a string, using the join() method.
To get the index of a character in a string, you use the indexOf() method, passing it the specific character as a parameter. This method returns the index of the first occurrence of the character or -1 if the character is not found.
TypeScript - String charAt() charAt() is a method that returns the character from the specified index. Characters in a string are indexed from left to right. The index of the first character is 0, and the index of the last character in a string, called stringName, is stringName.
What you want is charAt.
var x = 'some string'; alert(x.charAt(0)); // alerts 's' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
