function inArray(arr, k) {
    var out = false;
    var len = arr.length;
    while(len--) {
        if (arr[len] == k) out = true;
    }
    return out;
}

<script runat="server">

    Platform.Load("core", "1");

    try {

        var fruit = ["Apple", "Kiwi", "Tomato"];
		
        var result = inArray(fruit, "Tomato");

        Write(Stringify(result));
		
	} catch(error) {

        Write(Stringify(error));
        
    }

    function inArray(arr, k) {
        var out = false;
        var len = arr.length;
        while(len--) {

}

<script runat="server">

    Platform.Load("core", "1");

    try {

        var str = "the quick brown fox jumps over the lazy dog.";
		
        var result = capitalizeFirstLetter(str);

        Write(Stringify(result));
		
	} catch(error) {

        Write(Stringify(error));
        
    }

    function capitalizeFirstLetter(string) {
        return string.charAt(0).toUpperCase() + string.slice(1);
    }

</script>

sanitizeString

Removes extra spaces, carriage returns and line breaks

function sanitizeString(str) {

    var no_spaces = String(str).replace(/\s+/g, ' ');

    var no_breaks = String(no_spaces).replace(/(\r\n|\n|\r)/gm, '');

    return no_breaks;

}

<script runat="server">

    Platform.Load("core", "1");

    try {

        var str = "The  quick brown fox\n\r jumps over the     lazy dog.\n\r";
		
        var result = sanitizeString(str);

        Write(Stringify(result));
		
	} catch(error) {

        Write(Stringify(error));
        
    }

    function sanitizeString(str) {

        var no_spaces = String(str).replace(/\s+/g, ' ');

        var no_breaks = String(no_spaces).replace(/(\r\n|\n|\r)/gm, '');
