There are three different ways in which equal signs can be used in JavaScript:
1. = is the assignment operator
2. == is the equality operator
3. === is the strict comparison operator
These are each described in details as follows:
1. The assignment operator utilizes one equal sign (=). It is used to assign a value to a variable, as in x=1.
2. The equality operator makes use of two successive equal signs (==). It is used to determine if two operands are equal to each other.
var intTest = 1;
document.write(intTest=='1');
The preceding example returns true.
3. The strict comparison operator consists of three consecutive equal signs (===) and is used to determine if the operands are equal while also being of the same type.
var intTest = 1;
document.write(intTest==='1');
The preceding example returns false because a number is being compared to a string, even though they are both 1.
