What are some other ways to write JavaScript arrays?

Hello,

Are there other formats and configurations to write a JavaScript array? Note that there will be at least 100 pairs.

Code:

var thisArray = ["soda", "cake", "burger", "fries", "olive"]; 



var thatArray = ["aws1", "xzv2", "poi3", "gdf4", "lkj5"];

Each value must correspond to each other, and there can be no mismatch between values; the code will tend to be edited repeatedly after publishing.

In advance, I appreciate any help to this matter.

Better:

Code:

function pair( a, b )

{

    this.left = a;

    this.right = b;

}



var pairs = [

    pair("soda","awsl"), pair("cake","xzv2"), pair("burger","poi3"), ... 

   ];



// to iterate through them:

for ( var p = 0; p < pairs.length; ++p )

{

     var first = pairs[p].left;

     var second = pairs[p].right;

     ... do something with first and second ...

}

// (the names used there are of course entirely up to you)

Or, possibly even better:

Code:

// note the curly braces in place of square brackets!

pairs = {

    "soda" : "awsl", 

    "cake" : "xzv2", 

    "burger" : "poi3",

     ...

    };



// to iterate through them:

for ( var first in pairs )

{

    var second = pairs[first];

     ... do something with first and second ...

}
