Benchmark: Object.assign vs direct assignment Markus

Script Preparation code:

var data = {};

Tests:

Direct Assignment
for(var i = 0; i < 10000; i++) { data[`prop_${i}`] = true; }
Object.assign
for(var i = 0; i < 10000; i++) { var propName = `prop_${i}`; Object.assign(data, { [propName]: true }); }
test direct assignment
Object.fromEntries( Array(10000) .fill(true) .map((value, index) => [index, value]), )
test direct assignment second approach
Object.assign({}, Object.fromEntries( Array(10000) .fill(true) .map((value, index) => [index, value]), ))
