Generate javascript array with random strings

randomStringsArray.js

[...Array(10)].map(() => {
  const randomStr = "abcdefghijklmnopqrstuvwxyz".split('').sort(() => .5-Math.random()).join('');
  return randomStr.slice(0, Math.random()*26 + 2)
})

Another way I've found:

Array.apply(null, Array(10)).map(function() { 
  return Array.apply(null, Array(~~(Math.random() * 10  + 3))).map(function() {
    return String.fromCharCode(Math.random() * (123 - 97) + 97); 
  }).join('') 
});

ES2015

[...Array(10)].map(() =>  
 [...Array(~~(Math.random() * 10  + 3))].map(() =>
    String.fromCharCode(Math.random() * (123 - 97) + 97)
 ).join('') 
)
