charAt() not working second time in function for javascript

function translateWord(n)
for (var i = 0; i < n.length; i++)
if( n.charAt(i).toLowerCase() == "a")
return n.charAt(i) = "alpha ";





im trying to translate the letter at "i" into alpha but whenever i add the charAt(i) statement it just stops working?

note: im trying to translate the letter at "i" into alpha, not check if it is alpha

for example if i was to write 'aa' i want it to come out as 'alpha alpha'

return n.charAt(i) = "alpha ";

=

n.charAt(i)

How by doing something like this:

var mystring = "amazon";
mystring = mystring.split('a').join('alpha');
console.log(mystring);

Simple use String.replace()

String.replace()

function translateWord(n)
return n.replace('a','alpha');


console.log(translateWord('man'));

Method 1)

function translateWord(str, word, newWord)

var len = 0, newStr = '';

while (len < str.length)
newStr += ( str.charAt(len).toLowerCase() === word ) ? newWord : str[len];
len++;


return newStr;



console.log(translateWord('Amazon','a','alpha'));

Method 2)

function translateWord(str)
return str.replace(/a/gi,'alpha');


console.log(translateWord('Amazon'));
