remove ellement from array code example

Example 1: remove an element from array

var colors = ["red", "blue", "car","green"];

// op1: with direct arrow function
colors = colors.filter(data => data != "car");

// op2: with function return value
colors = colors.filter(function(data) { return data != "car"});

Example 2: remove one element using splice

fruits = ['Banana', 'Orange', 'Apple', 'Mango'];

removeFruitByIndex(index: number) {
  this.fruits = [
    ...this.fruits.slice(0, i),
    ...this.fruits.slice(i + 1, this.fruits.length),
  ];
}


removeFruitByValue(fruite: string) {
  const i = this.descriptionsList.indexOf(fruite);
  this.fruits = [
    ...this.fruits.slice(0, i),
    ...this.fruits.slice(i + 1, this.fruits.length),
  ];
}
