There are a few different ways to use JavaScript to determine whether a variable is a string. For primitive strings, the typeof operator is a simple method; for String objects, however, the instanceof operator is helpful. To achieve more accurate type checking, use Object.prototype.toString.call() for more sophisticated validation. Regular expressions can also verify if a string follows a particular format.
There are various ways to find out if a variable in JavaScript is undefined. One popular method for making sure the variable type is checked without producing errors is to use the typeof operator. Undefined variables can be handled in a modern, effective manner with the help of nullish coalescing, optional chaining, and default parameters.
Because JavaScript objects are automatically transformed to strings, storing them in HTML5 localStorage or sessionStorage can be challenging. You may efficiently manage object storage by using JSON.stringify() to serialize the object before storing it and JSON.parse() to deserialize it upon retrieval.
In JavaScript, making sure an array only has unique values is a typical task. When particular components, like zeroes, are present, difficulties could occur. We investigated a number of techniques, such as bespoke prototype methods and Set ways, to effectively eliminate duplicates.
