What are some other ways to write JavaScript arrays?

[Taro]

Hello,

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

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:

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:

// 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 ...
}
