Dynamic object literal in javascript?

Question

Is it possible to creat an object literal on the fly? Like this:

var arr = [ \'one\', \'two\', \'three\' ]; 

var literal = {}; 

for(var i=0;i

        

Answer 1

You can use for...of for the sake of simplicity:

for (const key of arr) {
   literal[key] = "";
}

Answer 2

Use this in your loop:

literal[arr[i]] = "";

Answer 3

for ( var i = 0, l = arr.length; i < l; ++i ) {
    literal[arr[i]] = "something";
}

I also took the liberty of optimising your loop :)
