There are several methods for concatenating string in javascript. Today we are going to understand 5 methods which I used and know. Lets start …
For example:
let string1 = "Hello";
let string2 = "World";
let concatenatedString = string1 + " " + string2;
console.log(concatenatedString); // Output: "Hello World"
For example:
let string1 = "Hello";
let string2 = "World";
let concatenatedString = string1.concat(" ", string2);
console.log(concatenatedString); // Output: "Hello World"
The concat() function is not commonly used due to the potential for errors. This can occur if concat() is applied to an array, resulting in unexpected behavior. It’s recommended to use the + operator instead unless there is a specific reason to use concat().
For example:
let string1 = "Hello";
let string2 = "World";
let concatenatedString = `${string1} ${string2}`;
console.log(concatenatedString); // Output: "Hello World"
For example:
let string1 = "Hello";
let string2 = "World";
let concatenatedString = [string1, string2].join(" ");
console.log(concatenatedString); // Output: "Hello World"
For example:
let string1 = "Hello";
let string2 = "World";
let concatenatedString = [...string1, ...string2].join(" ");
console.log(concatenatedString); // Output: "Hello World"
All of these methods will achieve the same result, but the plus operator and concat() method are the most commonly used.
