Secondly, What is == in code?

This is the symbol that says “equal to.” It’s referred to as a comparison operator.’ Text.length == text.length OR text.length == 4 OR 5 + 10 == 15 is an example. As far as I’m aware, Booleans(True or False data type) are used with comparison operators to decide whether or not a piece of code should execute.

Also, What does == === mean?

Only use === for complex type conversions. You’re probably aware that JavaScript has two distinct equality comparison operators: the === and == operators, sometimes known as triple equals and double equals.

People also ask, Should I use == or === in JavaScript?

In JavaScript, the == operator is used to compare two variables, but it ignores the variable’s datatype. The operator === is used to compare two variables, but it also examines the datatype and compares two values. Checks if two operands are equal without taking into account their type. Compares the types of two operands to see whether they are equivalent.

How does == vs === differ?

The distinction between == and === is that before comparing variables, == transforms them to the same type. This is referred to as type coercion. === performs no type conversion (coercion) and returns true only if the two variables being compared have the same values and types.

Why would you use === instead of ==?

If you want to compare two things in JavaScript, use ===. It’s called strict equality, and it means that this will return true if both the type and the value are the same, so there won’t be any unwanted type correction for you. If you use ==, you don’t care about the type and in many cases, you could face.

In Javascript, “==” is the equality operator. It tells the computer to compare two values and see if they are equal. If they are not equal, a message will be sent back to the program that used it.
