This shorthand method can save you lots of time and space when declaring multiple variables at the. ![]() ![]() Checks if the value of two operands are equal or not, if the values are not equal, then the condition becomes true. It’s good practice to declare your variable assignments at the beginning of your functions. All numbers in JavaScript are represented as floating-point values. The equals sign (British English, Unicode) or equal sign (American English), formerly known as the equality sign, is. In the above code snippet we have declared equal value to the variable a and to the operator, but we declared in different types, that means the value is given directly to the variable a and the value given to the operator is kept in inverted coma's, so the result gives 'false'. Note JavaScript does not make a distinction between integer values and floating-point values. Another good follow-up question is what would be result of comparing null and undefined using and operator in JavaScript. In the above code snippet we have given same type of values to the variable a and to the operator, so the result give 'true'.Īssigning same value in different types Assigning equal value and differnt type to the operator gives the result asĭocument.getElementById(" myId").innerHTML = ( a = "30") Assigning same type values Assigning equal value and equal type to the operator gives the result asĭocument.getElementById(" myId").innerHTML = (a = 30) The symbolic representation of equal value and equal type is =. JavaScript actually has two different representations for zero: positive zero, represented by +0 (or just 0), and negative zero, represented by -0. Equal value and equal type operator is an comparison operator which is used to check the whether two operands are having same value and same type.įor example, in the Equal operator we can write same value in different types gives the same result, like we declared var a = 5 and we are assigning a = 5 or a = "5" to the opertor gives the same result, but in Equal value and Equal type operator it is not possible. The comparison operators take simple values (numbers or string) as arguments and evaluate either true or false. Comparison Operators equal value and equal type x 5 not equal, x 8 not equal value or not equal type, x 5 not equal value or.
