How to find capitalized words and add a character before that in a given sentence using JavaScript?
Suppose, we have a string that contains some capitalized English alphabets like this −
const str = "Connecting to server Connection has been successful We found result";
We are required to write a JavaScript function that takes in one such string and inserts a comma ',' before the space before every capital letter in the string.
The code for this will be −
const str = "Connecting to server Connection has been successful We found
result";
const capitaliseNew = str => {
let newStr = '';
const regex = new RegExp(/.[A-Z]/g);
newStr = str.replace(regex, ',$&');
return newStr;
};
console.log(capitaliseNew(str));Following is the output on console −
Connecting to server, Connection has been successful, We found result
