Question

In javascript, why we use (==)?

Answer 1

== or === are to compare two elements (43==21 returns false beacuse 43 is not equal to 21), while the = is to assign a value to a variable.

Answer 2

if (youreName == myName) {
alert('COPYRIGHT ! ! !');
}

"42" == 42 // true
"42" === "42" // FALSE
42 === 42 // TRUE
