how to pass an array as an argument to a function in javascript code example

Example 1: how to pass an array to a function

// Program to calculate the sum of array elements by passing to a function 

#include <stdio.h>
float calculateSum(float age[]);

int main() {
    float result, age[] = {23.4, 55, 22.6, 3, 40.5, 18};

    // age array is passed to calculateSum()
    result = calculateSum(age); 
    printf("Result = %.2f", result);
    return 0;
}

float calculateSum(float age[]) {

  float sum = 0.0;

  for (int i = 0; i < 6; ++i) {
		sum += age[i];
  }

  return sum;
}

Example 2: js array as parameter

function myFunction(a, b, c) {//number of parameters should match number of items in your array
  	//simple use example
  	console.log("a: " + a);
  	console.log("b: " + b);
  	console.log("c: " + c);
}

var myArray = [1, -3, "Hello"];//define your array
myFunction.apply(this, myArray);//call function

Example 3: javascript function with array parameter

const args = ['test0','test1','test2'];
function call_me(param1, param2, param3){
  //
}
call_me.apply(this, args);

Example 4: make a parameter array in js

var x = [ 'p0', 'p1', 'p2' ]; 
call_me(x);

function call_me(params) {
  for (i=0; i<params.length; i++) {
    alert(params[i])
  }
}
