In JavaScript Array is basically an Object, but I want check exactly whether the given variable is Array or not.

When you make use of typeof to identify the Variable type on array, it always return an object, because in JavaScript array is a special type of object.

To solve this Issue, In 2009 new method is introduced, that is Array.isArray(), it takes an array as an argument and returns Boolean(true/false)

in addition to this, we can use instanceof operator, it returns true if an object is created by a given constructor.

Example To check JavaScript Variable is array or not

const arrData = [4,3,1,5,6,7,3,1];

console.log(arrData)

console.log(typeof arrData);  // object

console.log(Array.isArray(arrData));   // true

In JavaScript Language, We can iterate through an enumerable properties of an given object by using for...in loop. This loop will go through each element execute a block of code in the object.

for…in object javascript

Syntax

for (const key in object) {
  console.log(`${key}: ${object[key]}`);
}

Below is an example on How to use for...in loop to iterate the properties in an object {}:

const obj = {
  name: "Rajat",
  age: 27,
  country: "India"
};

for (const prop in obj) {
  console.log(`${prop}: ${obj[prop]}`);
}

Output of above code:

name: Rajat
age: 27
country: India

Here the for...in loop is similar to that of for...of loop, which is used to iterate over the values of an iterable object, For Example an array. But Note that, the for...in loop iterates over the properties of an object, while the for...of loop iterates over the values.

Here for..in loop will iterate the properties of the object and print the key and value of each property in the object defined.

for..of array javascript

Below is an example on how to make use of for...of loop to iterate value of an array:

const arr = [5, 2, 1, 3, 4];

for (const value of arr) {
  console.log(value);
}

This will output the following:

didChangeDependencies method in Flutter

In Flutter, The didChangeDependencies() override method comes in lifecycle of StatefulWidget. And is been called everytime whenever it see changes in dependencies of StatefulWidget.

For example, Let’s say a StatefulWidget depends on a inherited widget, and due to user event/action the value in inherited widget there is some changes occured, at that momentdidChangeDependencies method will be called to reflect the changes.

Below is a Example on how we can make use of didChangeDependencies in flutter:

class MyWidget extends StatefulWidget {
  @override
  _MyWidgetState createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  MyInheritedWidget _inheritedWidget;

  @override
  void didChangeDependencies() {
    _inheritedWidget = MyInheritedWidget.of(context);
    super.didChangeDependencies();
  }

  @override
  Widget build(BuildContext context) {
    // Use the inherited widget here
  }
}

In above example, the _MyWidgetState class is depended onMyInheritedWidget class, that is an inherited widget. basically didChangeDependencies method is used to fetch or detect value changes happens in the inherited widget, so that feather we can make use of it in the build method. Due to some event/action by user, If any value of the inherited widget changes, the didChangeDependencies method will be called immediately again, which make the StatefulWidget to update itself with the new value received in the inherited widget.

Note: It’s very important to call super.didChangeDependencies() at the end of the didChangeDependencies method, as it allows any ancestor widgets to also update their dependencies.

Comparing strings in java

In Java Programming language, There are two ways by which we can compare strings in java.

By using equals() method.
By using == operator.

Compare String using equal method in java

We can make use the equals() method to compare two strings. The equals() is an in-built method that is defined in the String class and only returns Boolean value (true/false) which indicating whether the given two strings are equal or not equal.

Below is an Example on How to use equals() method to compare two strings:

String str1 = "hello";
String str2 = "hello";

if (str1.equals(str2)) {
    System.out.println("The strings are equal.");
} else {
    System.out.println("The strings are not equal.");
}

Compare String using == operator in java

An Alternatively way, we can use the == operator to compare two strings. But note that this == will compares the references of the two strings rather than the contents of the strings themselves. As a result, it may not always produce the desired result.

Here’s an example of how to use the == operator to compare two strings:

String str1 = "hello";
String str2 = "hello";

if (str1 == str2) {
    System.out.println("The strings are equal.");
} else {
    System.out.println("The strings are not equal.");
}

In most of cases it is recommended to better use equals() method for comparing strings in java, because it always compares the contents instead of references.
