What is Assignment Operators in JavaScript and what is work and what it's used in JavaScript?

Answer 1

in simple words, the assignment operator works like this: when declaring a variable (using special words [var, let, or const]), space is reserved for data in the computer's memory area. but there is no data yet. this can be compared to a room and an empty box. a room is all the computer's memory, and a box is your variable. as long as there is no variable (you haven't declared it), the room is empty. and now comes the crucial moment... you have declared a variable! [let userName;] (a box was brought into the room). but your variable doesn't matter yet. it is empty (the box is empty, but"userName"is written on top of it). but from now on, the computer sees your variable. he can now manipulate her. if you try to output its value at this point, javascript will give you the answer: "undefined". to assign a value to a variable, use the "= " assignment operator. userName = "Johnny".you put the text (string value "Johnny")in the box (pc memory).
