javascript merge two array remove duplicate values
Solution: There are two different method first method: var array1 = ["a", "b"] var array2 = ["b", "c"] array1 = array1.concat(array2); console.log(array1); \\ output: ["a", "b", "c"] second method : let array1 = ["a", "b"]; let array2 = ["b", "c"]; let array3 = [...array1,...array2] \\ output:[ "a", "b", "b", "c" ] let array4=[...new Set(array3)] \\ hint: using the new Set method removes duplicate values from array console.log(array4); \\ output: ["a", "b", "c"]
