Lodash _.thru() method of Sequence in lodash is similar to _.tap() method and the only difference is that it returns the outcome of the interceptor. Moreover, this method is mainly used to “pass thru” values in a method chain sequence by replacing intermediate results.
Syntax:
_.thru(value, interceptor);Parameters:
- value: It is the value to be given to the interceptor.
- interceptor: It is the function to be called.
Return Value:
This method returns the result of the interceptor.
Example 1: In this example, we are getting a value as an array because of the use of the lodash _.thru() method.
// Requiring lodash library
const _ = require('lodash');
// Calling thru() method
let result = _(144).thru(function (value) {
return [value];
}).value();
// Displays output
console.log(result);
Output:
[ 144 ]Example 2: In this example, we are getting a value as an array because of the use of the lodash _.thru() method.
// Requiring lodash library
const _ = require('lodash');
// Calling thru() method
let result = _('GfG').thru(function (value) {
return [value];
}).value();
// Displays output
console.log(result);
Output:
[ 'GfG' ]Example 3: In this example, we are getting an array of array because of the use of the lodash _.thru() method.
// Requiring lodash library
const _ = require('lodash');
// Defining value
let val = ['g', 'f', 'G']
// Calling thru() method along with
// reverse and chain method
let result = _(val).reverse()
.chain()
.thru(function (value) {
return [value];
})
.value();
// Displays output
console.log(result);
