results array between two values - javascript

Related searches

i was wondering if there is a way to get an array with minimum and maximum values get by another array, or something like this:

var numbers = ['10','15','20','25','30','35','40','45','50'];  

var getnumbers = function(min,max){
 //return a result that is push to another array, in this case "results"

the output should give me something like 10 - 15 - 20 - 25 - 30

A slightly different approach, with a customized callback function for filtering.

function filterNumbers(min, max) {
    return function (a) { return a >= min && a <= max; };

var numbers = ['10', '15', '20', '25', '30', '35', '40', '45', '50'],
    result = numbers.filter(filterNumbers(10, 30));

document.write('<pre>' + JSON.stringify(result, 0, 4) + '</pre>');

Create array of all integers between two numbers, inclusive, in , In JavaScript ES6: start) / step) + 1 return Array(len).fill().map((_, idx) => start + ( idx * step)) } var result = range(9, 18 makes use of the fact that the function passes: 1. the value of the current´┐Ż JavaScript | array.values () The array.values () function is an inbuilt function in JavaScript which is used to returns a new array Iterator object that contains the values for each index in the array i.e, it prints all the elements of the array. It returns a new array iterator object i.e, elements of the given array.

try this

var numbers = ['10','15','20','25','30','35','40','45','50'];  
var output = "";
var getnumbers = function(min,max){
  for (var i = 0; i < numbers.length; i++){
    if(numbers[i] >= min && numbers[i] <= max){
      output += numbers[i] + "-";

JavaScript array: Generate an array between two integers of 1 step , function rangeBetwee(start, end) { if (start > end) { const arr = new Array(start - end + 1); for (let i = 0; i < arr. length; i++, start--) { resarrult[i] = start; } return arr; } else { const arro = new Array(end-start+1); for (let j = 0; j < arro. length; j++, start++) { arro[j] = start; } return arro; } } console. toString () converts an array to a string separated by a comma. join () combines all array elements into a string. concat combines two arrays together or add more items to an array and then return a new array. push () adds item (s) to the end of an array and changes the original array.

You can do something like: numbers.filter(function (value) { return value >= 10 && value <= 30 });

And if you really want the output to be N1 - N2 - N3 ... - NN, just do numbers.filter(function (value) { return value >= 10 && value <= 30 }).join(' - ');

range - Manual, If a step value is given, it will be used as the increment between elements in the here we want only array with 2 indexes with the values 1 and own number Result: // array (size=3) // 'length_prime_numbers' => int 5 // 'prime_numbers' => In Javascript, to compare two arrays we need to check that the length of both arrays should be same, the objects present in it are of the same type and each item in one array is equal to the counterpart in another array. By doing this we can conclude both arrays are the same or not.

JavaScript has inbuilt functions to solve this issue.

let numbers = ['10','15','20','25','30','35','40','45','50'];
// Get all elements between '10' and '30'
let result = numbers.splice(numbers.indexOf('10'),numbers.indexOf('30') + 1);
// If you want the answer to literally be '10-15-20-25-30'
let resultString = "";
for(const i in result){

Math.max(), 2. // expected output: 3. 3. . 4. console.log(Math.max(-1, -3, -2));. 5 find the maximum element in a numeric array, by comparing each value: This may be a source of confusion when we try to sort a list of numbers and get an unexpected result. The function, by default, converts the elements to strings (using String()). So an array like this [4, 3, 1, 10] will be sorted [1, 10, 3, 4] because the string '10' is bigger than '3'. Of course, string comparison is not always the desired case.

Indexed collections, An array is an ordered list of values that you refer to with a name and an index. results in the same array as this let arr = Array( arrayLength ) // This has exactly concat() joins two or more arrays and returns a new array. An array can hold many values under a single name, and you can access the values by referring to an index number. Creating an Array Using an array literal is the easiest way to create a JavaScript Array.

Given an unsorted array of n elements and also given two points num1 and num2. The task is to count number of elements occurs between the given points (excluding num1 and num2). If there are multiple occurrences of num1 and num2, we need to consider leftmost occurrence of num1 and rightmost occurrence of num2.

The result is a new array containing items from arr, then arg1, arg2 etc. If an argument argN is an array, then all its elements are copied. Otherwise, the argument itself is copied.

  • You can define a global array like numbers and push in it, or you can create a temp array in getnumbers and return it.
  • ok, get it, but i'm not sure how to get the numbers array value like the output.
  • I believe @Nina, answer is perfect, but an alternative could be looping over numbers array and pushing it into an array and return it.
  • also yours is very valid
  • you'd need to cast v to a number
  • It will be done automatically; the array is made up of strings. Weird JavaScript things, you know...
