Explain what the use of the with {} construct means in programming

In programming, the with {} construct is often used to create a block where you can access the properties or methods of an object without repeatedly specifying the object's name. For example, in Kotlin, with is a function that takes an object and a lambda expression, inside which you can work directly with that object.

Example in Kotlin:

val person = Person()
with(person) {
    name = "Ivan"
    age = 30
    printInfo()
}

Here, inside the with block, you can access the properties of person directly, without repeatedly specifying person.. This improves readability and reduces code clutter.

In other languages (for example, Pascal), with is used similarly to simplify access to record or object fields.
