F-strings (formatted string literals), introduced in Python 3.6, are a way to embed expressions inside string literals, using curly braces.
Capitalizing first letter of each word, the first letter of a sentence, or all caps lies in the specific style and purpose of text presentation.
Adding leading zeros to a number is often necessary in scenarios where the representation of the number needs to have a fixed width or format.
The main difference between `substring()` and `slice()` in JavaScript is how they handle negative or out-of-range arguments.
You can achieve string reversal using array manipulation methods like split, reverse, and join or through loops and other techniques.
You can use the % operator, format method, or f-strings to perform string interpolation, which is inserting values into a string in Python.
One of the basic operations in Swift is to compare two strings for equality or order. There are different ways to do that, depending on your needs.
JavaScript provides several approaches to achieve this, ranging from basic techniques to more advanced methods involving functions or regular expressions.
A binary number is a numeral system with a base of 2. It uses only two symbols, typically 0 and 1, to represent all values.
You can convert both strings to either lower case or upper case, use the localeCompare method of the String object, or regular expressions with the i flag.
