number {Number}: The number of times to repeat the string
returns {String}: Repeated string

Example

repeat('A', 5);
//=> AAAAA

Benchmarks

Repeat string is significantly faster than the native method (which is itself faster than repeating):

#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)
