Benchmark: Map lookup - MeasureThat.net

Script Preparation code:

let someMap = {}
for (let i = 0; i < 100; i++) {
    someMap[`${i}-test`] = i * 2
}

let someMapNumber = {}
for (let i = 0; i < 100; i++) {
    someMap[i] = i * 2
}

Tests:

string
let someMap = {} for (let i = 0; i < 100; i++) { someMap[`${i}-test`] = i * 2 } for (let i = 0; i < 100; i++) { console.log(someMap[`${i}-test`]) }
number
let someMapNumber = {} for (let i = 0; i < 100; i++) { someMapNumber[i] = i * 2 } for (let i = 0; i < 100; i++) { console.log(someMapNumber[i]) }
