What is == and === in TypeScript?
== : When comparing primitive values, like numbers and strings, this operator will apply a type conversion before doing the comparison. 1 == “1” evaluates to true . === : This operator does not do type conversions. If the types don’t match it will always return false .
Can you use == to compare strings?
In String, the == operator is used to comparing the reference of the given strings, depending on if they are referring to the same objects. When you compare two strings using == operator, it will return true if the string variables are pointing toward the same java object. Otherwise, it will return false .
How do you compare the values of two strings?
The compareTo() method compares the Unicode value of each character in the two strings you are comparing. compareTo() returns 0 if the string is equal to the other string, less than 0 if the string has fewer characters than the other string, and greater than 0 if the string has more characters than the other string.
What is the best way to compare strings?
Examples. The right way of comparing String in Java is to either use equals(), equalsIgnoreCase(), or compareTo() method. You should use equals() method to check if two String contains exactly same characters in same order. It returns true if two String are equal or false if unequal.
What is == and === in angular?
== compares two variables irrespective of data type while === compares two variables in a strict check, which means it checks for data type also then it returns true or false.
What does === mean?
The triple equals operator ( === ) returns true if both operands are of the same type and contain the same value. If comparing different types for equality, the result is false. This definition of equality is enough for most use cases. When comparing the string “0” and the number 0 the result is false as expected.

Which method is used to compare two strings ignoring the case?
The equalsIgnoreCase() method compares two strings, ignoring lower case and upper case differences. This method returns true if the strings are equal, and false if not. Tip: Use the compareToIgnoreCase() method to compare two strings lexicographically, ignoring case differences.
How do you compare two strings in an if statement?
You should use the equals() method of the String class to compare Strings. The == comparison only compares object references.
What is difference between == equals () and compareTo () method?
compareTo: Compares two strings lexicographically. equals: Compares this string to the specified object. compareTo compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly. equals() can be more efficient then compareTo().
Which is the most reliable expression for testing whether the values of two strings are the same?

What is == and equals in Java?
In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default it uses the equals(Object o) method of the closest parent class that has overridden this method.
