Sample JavaScript Before & After Beautification
Here is an example of how the beautifier cleans and formats messy JavaScript code:
Before:
function test(){console.log("VINAR TECH");let x=5; if(x>2){console.log("OK")}}
After Beautifying:
function test() {
console.log("VINAR TECH");
let x = 5;
if (x > 2) {
console.log("OK");
}
}
Use the editor above to beautify your own JavaScript code.
