Access array outside for loop

Question

I want to access array variable outside the loop. but its returning null. below is sample code.

var result = [];
for (var i=0; i < 10; i++) {
 result.push[i];
}

• Eddie: Use () on push. Like result.push(i)
• Jerodev: What exactly are you trying to do? result.push[i] does not do anything.
• DarkBee: Why doesn't push[i] return an error BTW? I'm curious
• nicholaswmin: @DarkBee because a function is an object in JS. array.push[2] = 'foo' creates a property 2 on the push method with value foo.
• DarkBee: @NicholasKyriakides Thank you for that insight :)

Answer 1

The syntex of push method is push() not push[].

var result = [];
for (var i=0; i < 10; i++) {
 result.push(i);
}
console.log(result);

For more info about push() look How to append something to an array?

• Jay: actually want achieve below code var args ={},fileObject = []; for (var i in files) { base64.encode('/opt/zipoutput/' + files[i], function (err, base64String) { convertval = base64String; var dataObj = { "actions": [ { "file_path": files[i] }] }; fileObject.push(dataObj); }); } console.log("fileObject111-----",fileObject);

Answer 2

push is a method implemented on array. The basic syntax of invoking or calling a function is to specify parenthesis () after the function name.

Array.prototype.push()

The push() method adds one or more elements to the end of an array and returns the new length of the array.

var result = [];
for (var i=0; i < 10; i++) {
 result.push(i);
}
console.log(result);

Answer 3

Please use the below code:

var result = []; 
for (var i=0; i < 10; i++) { 
 result.push(i); 
}

Answer 4

You can do that like this also.

var result = [];
 for (var i=0; i < 10; i++) {
 result[i]=i;
 }

If you want to use push then use like this result.push(i)
