single use array
30968.0 Ops/sec

Script Preparation code:
var a1 = new Array(100000); var a2 = new Array(100000); var a3 = new Float64Array(100000); for (let i = 0; i < 100000; ++i) { const x = Math.random(); a1[i] = x < 0.5 ? Math.random().toString() : x; a2[i] = Math.random(); a3[i] = Math.random(); }
Tests:
mixed use array
for (let i = 0; i < 10000; ++i) { const m = (Math.random() * 10000) | 0; a1[m] = a1[m] + Math.random(); }
single use array
for (let i = 0; i < 10000; ++i) { const m = (Math.random() * 10000) | 0; a2[m] = a2[m] + Math.random(); }
typed array
for (let i = 0; i < 10000; ++i) { const m = (Math.random() * 10000) | 0; a3[m] = a3[m] + Math.random(); }
