Assign two variables to the same value with one expression?

 

This question already has an answer here:

  • Multiple left-hand assignment with JavaScript 6 answers

    • There is absolutely no reason to prefer the destructuring assignment over simply 

    let x = 'hi', y = x;

    Not only it's one statement instead of two, but it also avoids extra allocations (the provided solution with destructuring allocates at least one object with no good reason).

    Yes, it is possible: 

    let x, y;
x = y = 'hi';

    It is called chaining assignment, making possible to assign a single value to multiple variables.
    See more details about assignment operator.

    If you have more than 2 variables, it's possible to use the array destructing assignment: 

    let [w, x, y, z] = Array(4).fill('hi');

    你可以这样做..但我的建议尽量避免它。 

    var one, two, three;
one = two = three = "";
