To use the xorBy
function from lodash in JavaScript, you first need to import it into your project. You can do this using the import statement:
index.tsx34 chars2 lines
Once you have imported the function, you can use it to perform an XOR operation on two or more arrays. The xorBy
function takes two or more arguments:
Additionally, xorBy
function also takes a function that determines how to compare the values in each array. This function should take a single argument and return a value that will be used to compare against the other arrays. For example:
index.tsx183 chars8 lines
In this example, the xorBy
function compares the three arrays and returns an array containing elements that exist in only one of the arrays. The function used to compare the values simply returns the value itself (i.e. the identity function), so each value is compared directly with the values in the other arrays. The resulting array contains 1
, 2
, and 7
, which are the values that exist in only one of the three input arrays.
