Script Preparation code:

var source = [...(new Array(1000))].map((v, i) => [`a${i}`, i]);

Tests:

Mutate
const output = {}; for (let i = 0; i < source.length; i++) { output[source[i][0]] = source[i][1]; } // Perform some work to prevent test optimizations Object.keys(output).length
Reduce
const output = source.reduce((acc, [key, val]) => ({ ...acc, [key]: val, }),{}); // Perform some work to prevent test optimizations Object.keys(output).length
fromEntries
const output = Object.fromEntries(source); // Perform some work to prevent test optimizations Object.keys(output).length
