## Benchmarks
|
||
|
|
|
||
|
|
Repeat string is significantly faster than the native method (which is itself faster than [repeating](https://github.com/sindresorhus/repeating)):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
#1: 5
|
||
|
|
native x 10,484,023 ops/sec ±1.24% (89 runs sampled)
|
||
|
|
repeat-string x 16,189,255 ops/sec ±1.05% (91 runs sampled)
|
||
|
|
repeating x 9,051,715 ops/sec ±1.18% (90 runs sampled)
|
||
|
|
|
||
|
|
#2: 50
|
||
|
|
native x 7,975,566 ops/sec ±1.29% (91 runs sampled)
|
||
|
|
repeat-string x 15,317,972 ops/sec ±1.16% (87 runs sampled)
|
||
|
|
repeating x 6,279,112 ops/sec ±1.29% (89 runs sampled)
|
||
|
|
|
||
|
|
#3: 250
|

|
|
native x 6,212,752 ops/sec ±1.33% (91 runs sampled)
|
||
|
|
repeat-string x 14,565,168 ops/sec ±0.83% (93 runs sampled)
|
||
|
|
repeating x 5,787,124 ops/sec ±1.25% (92 runs sampled)
|
||
|
|

|
|
native x 4,912,163 ops/sec ±1.27% (91 runs sampled)
|

|
|
repeat-string x 17,129,748 ops/sec ±1.01% (91 runs sampled)
|
||
|
|
repeating x 4,613,043 ops/sec ±1.37% (91 runs sampled)
|

repeat-string x 14,877,672 ops/sec ±1.00% (93 runs sampled)
|
||
|
|
repeating x 4,305,756 ops/sec ±1.36% (89 runs sampled)
