• In this lesson, we will explore basic types of programming languages, focusing on the string type and operations defined on strings.
• Strings in programming languages are a data type which is a sequence of characters that can be assigned to variables, accessed and manipulated using various properties and methods in order to perform various operations.
• Strings in JavaScript can be declared using either single or double quotation marks, as demonstrated in the following code block.
• Indexing is an important concept when manipulating strings, as they are indexed starting from 0 and not 1.
• Yes, the code block is valid and declares a string with a value of "India".
• Strings in most programming languages can contain both lowercase and uppercase letters, and case is important in the output of the code.
• String operations are defined on different data types, including strings, to perform comparison, combination, removal, and addition of characters/strings.
• In JavaScript, strings can be manipulated through concatenation, properties such as length, indexOf and toLowerCase(), as outlined in the documentation provided by the Mozilla Developer Network.
• The code block combines two strings using string concatenation, resulting in Sara12 as the output.
• The code will output the index position of the letter f in the animal variable, which is 4.
• Strings are immutable and must be declared with double quotation marks to include single quotation marks inside.
• We learned about string operations and their benefits, which can help us modify strings without having to recreate them.
