find method javascript

// .find method only accepts a callback function 
// and returns the first value for which the function is true.
const cities = [
  "Orlando",
  "Dubai",
  "Denver",
  "Edinburgh",
  "Chennai",
  "Accra",
  "Denver",

//Expected output is 4 (first instance of "Denver" in array)

find in javascript

// Same Code Using Arrow function & destructuring technique

const inventory = [
  {name: 'apples', quantity: 2},
  {name: 'bananas', quantity: 0},
  {name: 'cherries', quantity: 5}
];

const result = inventory.find( ({ name }) => name === 'cherries' );   // ({name})==> destructuring technique

console.log(result); // { name: 'cherries', quantity: 5 }

find js

The find() method returns the value of the first element in the provided array that satisfies the provided testing function. If no values satisfy the testing function, undefined is returned.

find in js

The first element that will be found by that function
const f = array1.find(e => e > 10);

find in javascript js

//find is higher oder function that return only if condition is true
const names= ["Shirshak","SabTech","Kdc"]
const searchName = names.find(function(name){
return names.inclues("Shirshak")
})

find in javascript

str.indexOf("locate"); // return location of first find value
str.lastIndexOf("locate"); // return location of last find value
str.indexOf("locate", 15); // start search from location 15 and then take first find value
str.search("locate");
//The search() method cannot take a second start position argument. 
//The indexOf() method cannot take powerful search values (regular expressions).

js find

const array1 = [5, 12, 50, 130, 44];

const isLarger = (element) => element > 45 ;

const found = array1.find(isLarger);

console.log(found);
//output 50

What is the find() method? in Javascript

/* This method returns first element of the array that satisfies the condition
	specified in the callback function.
*/

const x = [1, 2, 3, 4, 5];

const y = x.find(el => el*2 === 2);

console.log("y is: ", y); // y is: 1

/* Now, if you see the output of the above example, the value of y is 1.
	This is because the find() method searches for first element in the array
    that satisfies the condition specified.
