JavaScript Code:
function add_two_int_without_carrying(n1, n2) {
var result = 0,
x = 1;
while (n1 > 0 && n2 > 0) {
result += x * ((n1 + n2) % 10);
n1 = Math.floor(n1 / 10);
n2 = Math.floor(n2 / 10);
x*= 10;
}
return result;
}
console.log(add_two_int_without_carrying(222, 911))
console.log(add_two_int_without_carrying(200, 900))
Sample Output:
133 100

JavaScript: Tips of the Day
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"
