question about concatenation

[espace]

hi,

i want to do this :

l0.a=0

l1.a=1

so i do this :

for (var i = 0; i < 2; i++){'l'+i={a:i}}

but it say ReferenceError: invalid assignment left-hand side

how do you that ?

nice way

var l = [];

for (var i=0; i < 2; i++)
{
  l.push( { a : i } );
}

console.log(l[0], l[1]);

in this case, this === window -> better not pollute it, but you can use it on your own object without worries

for (var i=0; i < 2; i++)
{
  this[ 'l' + i ] = { a : i };
}

console.log(this);
console.log(this.l0, this.l1);

nasty way

for (var i=0; i < 2; i++)
{
  eval( 'l' + i + ' = { a : i } ' );
}

console.log(l0, l1);

Do you mean this...

        for (var i=0; i < 2; i++)
        {
          console.log('1' + i.toString() + '.a=' + i.toString()); ;
        }

Returns...

10.a=0
11.a=1
