# How to add a character to the beginning of every word in a string in JavaScript?

We are required to write a function that takes in two strings, we have to return a new string which is just the same as the first of the two arguments but have second argument prepended to its every word.

For example −

Input → ‘hello stranger, how are you’, ‘@@’
Output → ‘@@hello @@stranger, @@how @@are @@you’

If second argument is not provided, take ‘#’ as default.

## Example

const str = 'hello stranger, how are you';
const prependString = (str, text = '#') => {
return str
.split(" ")
.map(word => ${text}${word})
.join(" ");
};
console.log(prependString(str));
console.log(prependString(str, '43'));

## Output

The output in the console will be −

#hello #stranger, #how #are #you
43hello 43stranger, 43how 43are 43you
