The same above rules are applicable while using the Strict not equal ( !=) and Not equal ( !=) operators as well.

#Javascript does not equal sign code

It’s not only safe, but it also simplifies your code and improves readability.

In any other cases, you’re safe to use =.

If a value in comparison could be any of these specific values ( 0, "", or – empty array), use = instead of =.

If a value in comparison could be either true or false value, use = and not =.

In connection with JavaScript, below are some use cases where you can use either of the = or = operators. When to Use an Operator for String Equality in JavaScript But the way it works in JavaScript is a little bit different than other languages. You might already have seen the 3rd and the 4th operator, i.e., = and !=, which are pretty common in other programming languages as well. Out of these four operators, let’s figure out the best one for checking the string equality depending on the use cases. These operators are used not just for checking the string equality but also for checking the equality of other data types. If the values match with each other, then it returns false. It returns true only if the values inside the variables don’t match, irrespective of their data type.

Not Equal ( !=): This is the opposite of Equal ( =).

If the value matches,it returns true, else it returns false.

Equal ( =): The double equal sign checks only the value of a variable.

If either value or the data type does not match, it returns true otherwise, false.

Strict not equal ( !=): This is the opposite of Strict equal.If both of these things are equal, then it only returns true, else it returns false. Strict equal ( =): The Strict equal (also known as the triple equals operator) checks the value of the variable and its data type.These operators are called the comparison operators. In JavaScript, there are four operators you can use for checking string equality. Understand String Equality in JavaScript with Examples.When to Use an Operator for String Equality in JavaScript.
