Question

what is the proper way to declare a variable?
answer 1
var name \john doe\;
answer 2
var = \john doe\;
answer 3
var name = \john doe\;
answer 4
var name == \john doe\;

Explanation:

When declaring a variable in programming (in JavaScript, for example), the correct syntax is to use the keyword (like var in older JavaScript) followed by a variable name and then an assignment operator (=) to assign a value. Answer 1 is missing the assignment operator. Answer 2 is missing the variable name. Answer 4 uses a triple equal (===) which is a comparison operator (used for strict equality checks, not assignment).
