I am very new to JavaScript. Presently, I am doing a Program where I want to translate a text into "rovarspracket". ie) Double every consonant and place an occurrence of "o" in between. For ex: , translate("this is fun") should return the string "tothohisos isos fofunon" . I am not able to get the result as desired. Help me that i would learn.
This is my following code which i tried.
<button type="button" onclick="translate('de')">try it</button>
<h2 id="ad" />
<script>
function translate(t)
{//alert(t.length);exit;
var l=t.length;
var v=["a","e","i","o","u",""];
var b="";
for(var i=0;i<l;i++)
{ //alert(i);exit;
var c=t.charAt[i];alert(c);
if(v.indexOf(c)!=-1)
{
b=(b+(c));
}
else
{
b=(b+(c="o"+c));
}
}
document.getElementById("ad").innerHTML=b;
}
</script>
I've taken the liberty to simplify the functionality for you:
var str = "this is fun", arr = str.split(''); // Split the string into an array of separate characters. mapped = arr.map(function(c){ if(["a","e","i","o","u"," "].indexOf(c) == -1) // If the character is a consonant return c + 'o' + c; // replace it, return c; // otherwise, just keep the current character. }), result = mapped.join(''); // Rebuild the string console.log(result);
Or, a little more compact:
var str = "this is fun", result = str.split('').map(function(c){ return (["a","e","i","o","u"," "].indexOf(c) == -1) ? (c + 'o' + c) : c; }).join(''); console.log(result);
This is something you could do.
function translate(input) { var outputString = []; var vowels = ['a', 'e', 'i', 'o', 'u']; input.split("").forEach(function(charValue) { if (vowels.includes(charValue) || charValue == ' ') { outputString.push(charValue); } else { outputString.push(charValue + 'o' + charValue); } }); document.querySelector("#output").innerHTML = outputString.join(""); }
div { padding: 10px; }
<button type="button" onclick="window.translate('this is fun')">try it</button> <div id="output"></div>
If you are specifically looking a solution with charAt function, here it is.
function translate(input) { var outputString = [], vowels = ['a', 'e', 'i', 'o', 'u']; for (var idx = 0; idx < input.length; idx++) { var currentChar = input.charAt(idx); if (vowels.indexOf(currentChar) === -1 && currentChar != " ") { outputString.push(currentChar + "o" + currentChar); } else { outputString.push(currentChar); } } console.log(outputString.join("")); } translate("this is fun");
