• javascript

• 1 And how these texts are placed in html? – Nikhil Aggarwal Commented Jan 14, 2016 at 19:06
• Need a little more detail about what this text is. Are these lines in a javascript array? Are they in separate html elements in a web page? All in one HTML element? – Ryan Commented Jan 14, 2016 at 19:08
• 1 Is it a single string with newline characters or separate strings for each line? – theUtherSide Commented Jan 14, 2016 at 19:09

You can do this with regular expresion (.replace(/^/gm, '????')):

> str = "Man like dog.\nMan like to drink\nMan is the king."
'Man like dog.\nMan like to drink\nMan is the king.'
> str = str.replace(/^/gm, '????')
'????Man like dog.\n????Man like to drink\n????Man is the king.'
> console.log(str)
????Man like dog.
????Man like to drink
????Man is the king.

Storing the text in an array you can modify each element of the array like this

var text = ['Man like dog.', 'Man like to drink.', 'Man is the king.'];

console.log(text.join('\n'));

text = text.map(function(element){ return '????' + element;});

console.log(text.join('\n'));

assuming you have an input with the string (having newline separators) which you want to process

var array = input.split(/\n/);

var newArray = [];
array.forEach( function(element){

   newArray.push( "????" + element );

} );
console.log( newArray );
