Vanilla-JS way of generating a dice roll.
const diceRoll = (low, high) => {
return Math.floor(Math.random() * high) + low;
}
diceRoll(1, 50);
Rando.js makes it easier.
rando() //a floating-point number between 0 and 1 (could be exactly 0, but never exactly 1)
rando(5) //an integer between 0 and 5 (could be 0 or 5)
rando(5, 10) //a random integer between 5 and 10 (could be 5 or 10)
rando(5, "float") //a floating-point number between 0 and 5 (could be exactly 0, but never exactly 5)
rando(5, 10, "float") //a floating-point number between 5 and 10 (could be exactly 5, but never exactly 10)
rando(true, false) //either true or false
rando(["a", "b"]) //{index:..., value:...} object representing a value of the provided array OR false if array is empty
rando({a: 1, b: 2}) //{key:..., value:...} object representing a property of the provided object OR false if object has no properties
rando($("div")) //{index:..., value:...} object representing a jQuery element from the provided jQuery element set OR false if the provided jQuery element set does not contain any elements
rando("Gee willikers!") //a character from the provided string OR false if the string is empty. Reoccurring characters will naturally form a more likely return value
rando(null) //ANY invalid arguments return false
randoSequence(5) //an array of integers from 0 through 5 in random order
randoSequence(5, 10) //an array of integers from 5 through 10 in random order
randoSequence(["a", "b"]) //an array of {index:..., value:...} objects representing the values of the provided array in random order
randoSequence({a: 1, b: 2}) //an array of {key:..., value:...} objects representing the properties of the provided object in random order
randoSequence($("div")) //an array of {index:..., value:...} objects representing all jQuery elements from the provided jQuery element set in random order
randoSequence("Good gravy!") //an array of the characters of the provided string in random order
randoSequence(null) //ANY invalid arguments return false
