Benchmark: Lodash Set performance

HTML Preparation code:


<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.21/lodash.min.js'></script>

Script Preparation code:

var obj = {
    a: {
        b: [ { c: 'Before' } ]
    }
};

function setValue(obj, path, value) {
  var a = path.split('.')
  var o = obj
  while (a.length - 1) {
    var n = a.shift()
    if (!(n in o)) o[n] = {}
    o = o[n]
  }
  o[a[0]] = value
}

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
async function globalMeasureThatScriptPrepareFunction() {
    // This function is optional, feel free to remove it.
    // await someThing();
}

Tests:

Lodash
_.set(obj, "a.b.0.c", "After");
Simple
setValue(obj, "a.b.0.c", "After");
