javascript concat function code example

Example 1: string concat javascript

//This method adds two or more strings and returns a new single string.

let str1 = new String( "This is string one" ); 
let str2 = new String( "This is string two" ); 
let str3 = str1.concat(str2.toString());
console.log("str1 + str2 : "+str3)

output:
str1 + str2 : This is string oneThis is string two

Example 2: javascript push and concat

//push() adds element in the end of array
// concat() also the same, but if the element is array, that element will probably separate elements of itself in the end of the array

Example 3: concat()
