To use the bind()
function from the Underscore library in TypeScript, you need to install the Underscore library and include it in your project as a module. Then, you can call the bind()
function on any function object to bind it to a specific object.
Here's an example of how to do it:
index.ts267 chars17 lines
In this example, we define an interface MyObject
that has a name
property and a greeting()
method. We create an object obj
that implements this interface, and define the greeting()
method to log a greeting message to the console.
Next, we use the _.bind()
function to create a new function boundFn
that is bound to the obj
object. We pass in obj.greeting
as the function to bind, and obj
as the object to bind it to.
Finally, we call the boundFn()
function to execute the bound function, which logs the greeting message to the console.
Note that without the use of _.bind()
, obj.greeting()
would cause TypeScript to raise an error because the this
keyword would not refer to the obj
object. The _.bind()
function solves this issue by creating a new function with a fixed this
value.
