Write a JavaScript program to compute the sum and product of an array of integers.
Pictorial Presentation:

Sample Solution:
HTML Code:
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Compute the sum and product of an array of integers</title>
</head>
<body>
</body>
</html>
JavaScript Code:
var array = [1, 2, 3, 4, 5, 6],
s = 0,
p = 1,
i;
for (i = 0; i < array.length; i += 1)
{
s += array[i];
p *= array[i];
}
console.log('Sum : '+s + ' Product : ' +p);
Sample Output:
Sum : 21 Product : 720
Flowchart:

ES6 Version:
const array = [1, 2, 3, 4, 5, 6];
let s = 0;
let p = 1;
let i;
for (i = 0; i < array.length; i += 1)
{
s += array[i];
p *= array[i];
}
console.log(`Sum : ${s} Product : ${p}`);

Converts a string to title case
Example:
const toTitleCase = str => str .match(/[A-Z]{2,}(?=[A-Z][a-z]+[0-9]*|\b)|[A-Z]?[a-z]+[0-9]*|[A-Z]|[0-9]+/g) .map(x => x.charAt(0).toUpperCase() + x.slice(1)) .join(' '); console.log(toTitleCase('some_database_field_name')); // 'Some Database Field Name' console.log(toTitleCase('Some label that needs to be title-cased')); // 'Some Label That Needs To Be Title Cased' console.log(toTitleCase('some-package-name')); // 'Some Package Name' console.log(toTitleCase('some-mixed_string with spaces_underscores-and-hyphens')); // 'Some Mixed String With Spaces Underscores And Hyphens'
Output:
"Some Database Field Name" "Some Label That Needs To Be Title Cased" "Some Package Name" "Some Mixed String With Spaces Underscores And Hyphens"
