HTML Preparation code:

<div id="test"></div>

Script Preparation code:

el = document.getElementById("test");

Tests:

style.setProperty
let i = 0; while (i < 10000) { el.style.setProperty("color","red"); el.style.setProperty("border","1vmin solid red"); el.style.setProperty("padding","0.5vmin"); el.style.setProperty("background-color","black"); el.style.setProperty("height","1vh"); el.style.setProperty("width","1vw"); i++; }
style.cssText
let i = 0; while (i < 10000) { el.style.cssText = "color:red;border:1vmin solid red;padding:0.5vmin;background-color:black;height:1vh;width:1vw;"; i++; }
style
let i = 0; while (i < 10000) { el.style = "color:red;border:1vmin solid red;padding:0.5vmin;background-color:black;height:1vh;width:1vw;"; i++; }
Object.assign
let style = { height: '1vh', width: '1vw', color: 'red', border: '1vmin solid red', backgroundColor: 'black', padding: '0.5vmin' }; let i = 0; while (i < 10000) { Object.assign(el.style, style); i++; }
setAttribute
let i = 0; while (i < 10000) { el.setAttribute('style',"color:red;border:1vmin solid red;padding:0.5vmin;background-color:black;height:1vh;width:1vw;"); i++; }
direct assignment
let i = 0; while (i < 10000) { el.style.height = '1vh'; el.style.width = '1vw'; el.style.color = 'red'; el.style.border = '1vmin solid red'; el.style.backgroundColor = 'black'; el.style.padding = '0.5vmin'; i++; }
