To remove listener from outer function, use removeEventListener().ExampleFollowing is the code − Document Press Me var demoId = document.getElementById('demo'); demoId.addEventListener('click', function fun() { outerFunction(this, fun); }, false); function outerFunction(self, funct) { console.log('outer function is called....'); self.removeEventListener('click', funct, false); console.log("Listener has been removed...") } To run the above program, save the file name anyName.html(index.html) and right click on the file. Select the option “Open with live server” in VS Code editor.OutputThis will ... Read More
To merger properties of two objects, you can use the concept of {...object1,...object2,... N).ExampleFollowing is the code −var firstObject = { firstName: 'John', lastName: 'Smith' }; var secondObject = { countryName: 'US' }; var mergeObject = {...firstObject, ...secondObject}; console.log(mergeObject);To run the above program, you need to use the following command −node fileName.js.Here, my file name is demo307.js.OutputThis will produce the following output −PS C:\Users\Amit\javascript-code> node demo307.js { firstName: 'John', lastName: 'Smith', countryName: 'US' }
You can use your own function to get all combinations.ExampleFollowing is the code −function combination(values) { function * combinationRepeat(size, v) { if (size) for (var chr of values) yield * combinationRepeat(size - 1, v + chr); else yield v; } return [...combinationRepeat(values.length, "")]; } var output = combination([4,5]); console.log(output);To run the above program, you need to use the following command −node fileName.js.Here, my file name is demo306.js.OutputThis will produce the following output −PS C:\Users\Amit\javascript-code> node demo306.js [ '44', '45', '54', '55' ]
We are required to write a function that compares two arrays and creates a third array filling that array with all the elements of the second array and filling null for all those elements that are present in the first array but misses out in the second array.For example:If the two arrays are −const arr1 = ['f', 'g', 'h']; const arr2 = ['f', 'h'];Then the output should be −const output = ['f', null, 'h'];Therefore, let’s write the code for this function −ExampleThe code for this will be −const arr1 = ['f', 'g', 'h']; const arr2 = ['f', 'h']; const compareAndFill ...

Given an array of integers, we are required to write a function that takes this array and finds the one element that appears an odd number of times.There will always be only one integer that appears an odd number of times. We will approach this problem by sorting the array. Once sorted, we can iterate over the array to pick the element that appears for odd number of times.ExampleThe code for this will be −const arr = [20, 1, -1, 2, -2, 3, 3, 5, 5, 1, 2, 4, 20, 4, -1, -2, 5]; const findOdd = arr => { ...
