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
