Benchmark: random String for loop vs while loop

Tests:

for loop
function randomString( length = 10, allowed = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" ) { let result = "" for (let i = 0; i < length; i++) { result += allowed.charAt(Math.floor(Math.random() * allowed.length)) } return result } randomString();
while loop
function foo( length = 10, allowed = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789" ) { let result = "" let i=0; do { result += allowed.charAt(Math.floor(Math.random() * allowed.length)) i +=1; } while(i < length) return result } foo();
