How to iterate over arrays and objects in JavaScript [duplicate]

Answer 1

Use Array#forEach method for array iteration.

var points = [{
  x: 75,
  y: 25
}, {
  x: 75 + 0.0046,
  y: 25
}];

points.forEach(function(obj) {
  console.log(obj.x, obj.y);
})

Answer 2

You can use for..of loop.

var points = [{ x: 75, y: 25},{ x: 75+0.0046, y: 25}];
for (let point of points) {
    console.log(point.x, point.y);
}

Answer 3

var points = [{ x: 75, y: 25},{ x: 75+0.0046, y: 25}];

//ES5
points.forEach(function(point){ console.log("x: " + point.x + " y: " + point.y) })


//ES6
points.forEach(point=> console.log("x: " + point.x + " y: " + point.y) )
