Comparing the Number of Object Properties in Arrays: Quality over Quantity

I am creating detailed character descriptions that are rich in strings using the character object below. Efficiency is a key factor for me, as I am aware that arrays with lengthy strings can become top-heavy quickly. Assuming that properties can be accessed easily in both scenarios and the values are the same, are there any significant variations in efficiency between the two objects presented below?

this.genphysdesc = genphysdesc;
this.facetype = facetype;
this.bodytype = bodytype;
this.haircol = haircol;
this.gender = gender;
this.pronA = pronA;
this.pronB = pronB;
this.pronC = pronC;
this.pronD = pronD;

VS.

this.physdesc = [genphysdesc, facetype, bodytype, haircol]
this.gender = [gender, pronA, pronB, pronC, pronD]

In both cases, the values will consist of strings ranging from approximately 5 to 35 characters each.

Please let me know if you require further clarification. Thank you for your assistance!

Answer №1

The first scenario involved the utilization of objects, while the second scenario employed arrays.

If we focus on analyzing the variances between arrays:

// Delving into Hoisting
var a = [];
var propA, propB, propC, propD, propE, propF;
propA = 1;
propB = 2;
propC = 3;
propD = 4;
propE = 5;
propF = 6;

a.push( propA );
a.push( propB );
a.push( propC );
a.push( propD );
a.push( propE );
a.push( propF );

// as opposed to

a = [ propA, propB, propC, propD, propE, propF ];

console.log( a );

In the second version, assignment occurs only once, rendering it more efficient. Object assignment would essentially be identical but with different syntax.

Consider investigating hoisting further:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/var

Performance discrepancies and comparisons exist for [] versus push syntax: Is there a reason JavaScript developers don't use Array.push()?
