***
$("#regTitle").html("Hello World");
***

You could use search or match for this.
***
str.search( 'Yes' )
***

will return the position of the match, or -1 if it isn't found.

***
console.log(
[1, 2, 3, 4].reduce((a, b) => a + b, 0)
)
console.log(
[].reduce((a, b) => a + b, 0)
)
***

This is a simple reference:
***
// this is the id of the form
$("#idForm").submit(function(e) {

e.preventDefault(); // avoid to execute the actual submit of the form.

var form = $(this);
var url = form.attr('action');

$.ajax({
type: "POST",
url: url,
data: form.serialize(), // serializes the form's elements.
success: function(data)
{
alert(data); // show response from the php script.
}
});


});

Use *numpy.set_printoptions*:
***
import sys
import numpy
numpy.set_printoptions(threshold=sys.maxsize)
***

You can use *pandas*. It does take some extra memory so it's not always possible, but it's very fast and easy to use.
***
import pandas as pd
pd.DataFrame(np_array).to_csv("path/to/file.csv")
***
if you don't want a header or index, use to_csv("/path/to/file.csv", header=None, index=None)

Checking for undefined-ness is not an accurate way of testing whether a key exists. What if the key exists but the value is actually undefined?
***
var obj = { key: undefined };
obj["key"] !== undefined // false, but the key exists!
***
You should instead use the in operator:
***
"key" in obj // true, regardless of the actual value
***
If you want to check if a key doesn't exist, remember to use parenthesis:
***
!("key" in obj) // true if "key" doesn't exist in object
!"key" in obj // Do not do this! It is equivalent to "false in obj"
***
Or, if you want to particularly test for properties of the object instance (and not inherited properties), use hasOwnProperty:
***
obj.hasOwnProperty("key") // true
***
For performance comparison between the methods that are in, hasOwnProperty and key is undefined, see this benchmark

Always check the standard libraries first.
***
import java.util.Arrays;
***
Then try:
***
System.out.println(Arrays.toString(array));
***
or if your array contains other arrays as elements:
***
System.out.println(Arrays.deepToString(array));
***

Your path only lists Visual Studio 11 and 12, it wants 14, which is Visual Studio 2015. If you install that, and remember to tick the box for Languages->C++ then it should work.

On my Python 3.5 install, the error message was a little more useful, and included the URL to get it from
***
error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools":
***
Edit: New working link

Edit: As suggested by Lightfire228, you may also need to upgrade setuptools package for the error to disappear:
***
pip install --upgrade setuptools

The three dots represent the spread operator in ES6. It allows us to do quite a few things in JavaScript:

Concatenate arrays
***
var shooterGames = ['Call of Duty', 'Far Cry', 'Resident Evil'];
var racingGames = ['Need For Speed', 'Gran Turismo', 'Burnout'];
var games = [...shooterGames, ...racingGames];

console.log(games) // ['Call of Duty', 'Far Cry', 'Resident Evil', 'Need For Speed', 'Gran Turismo', 'Burnout']
***
Destructuring an array
***
var shooterGames = ['Call of Duty', 'Far Cry', 'Resident Evil'];
var [first, ...remaining] = shooterGames;
console.log(first); //Call of Duty
console.log(remaining); //['Far Cry', 'Resident Evil']
***
Combining two objects
***
var myCrush = {
firstname: 'Selena',
middlename: 'Marie'
};

var lastname = 'my last name';

var myWife = {
...myCrush,
lastname
}

console.log(myWife); // {firstname: 'Selena',
// middlename: 'Marie',
// lastname: 'my last name'}
***
There's another use for the three dots which is known as Rest Parameters and it makes it possible to take all of the arguments to a function in as one array.

Function arguments as array
***
function fun1(...params) {

}
***

I am not sure if this will work for your situation, but often map is a good answer.

If this was your code with the for loop:

***
for (var i=0; i < objects.length; i++) {

}
***
You could write it like this with map:

***
{objects.map(function(object, i){
return ;
})}
***
ES6 syntax:

***
{objects.map((object, i) => )}
***

Hello,
Let us check into this issue, we will revert back soon !!
