Benchmark: pick by substring key fixed

Tests:

substring & array result
const object = {'key1': 'value1', 'key2': 'value2', 'key1 variant': 'value1 variant'} const result = [] const key='key1 variant' for (let i = 0; i <= key?.length; i++) { if (key[i] === ' ' || i === key.length) { const current = key.substring(0, i) if (object[current]) { result.push(object[current]) } } } const final = result.join(' ')
string builder & array result
const object = {'key1': 'value1', 'key2': 'value2', 'key1 variant': 'value1 variant'} const result = [] const key='key1 variant' let current = '' for (let i = 0; i <= key?.length; i++) { current += key[i] if (key[i] === ' ' || i === key.length) { if (object[current]) { result.push(object[current]) } } } const final = result.join(' ')
