JavaScript Closure

In JavaScript, closures are created every time a function is created, at function creation time.

 

Closure means that an inner function always have access to the variables and parameters of its outer function even after the outer function has returned. This is not common with other programming languages.

Sample Code:
function simpleFunc() {

  let strName = 'Magulan';
 
  function showName() {
 
    alert( strName);
    
  }
 
  return showName;
 
}

var myFunc = simpleFunc();
myFunc();//alerts Magulan which is outer function variable.

It shouldn't alert Magulan since the strName is a variable from outer function. It is alerting because of closures. A closure is the combination of a function and the lexical environment within which that function was declared. This environment consists of any local variables that were in-scope at the time the closure was created.

Another Sample Code:
function add( x ) {

  return function( y ) {
 
    return x + y;
    
  };
 
}

let obj = add( 2 );
alert( obj( 3 ) );//alerts 5

CSS Updates to SLDS in Lightning Web Component Salesforce

Salesforce Lightning Design System (SLDS) styling hooks make it easy to customize component styling and express your brand. Styling hooks provide CSS custom properties that correspond to SLDS component blueprints and design variations. To customize an SLDS style, declare a corresponding custom property in a component’s style sheet. You can use the custom properties to style base components and custom components.

 

Sample Code:

HTML:
<template>
    <lightning-card>
        <lightning-button
            variant="brand"
            label="Submit">
        </lightning-button>
    </lightning-card>
</template>

JavaScript:
import { LightningElement } from 'lwc';

export default class SampleLWC extends LightningElement {

}

CSS:
:host {
    --sds-c-button-brand-color-background: black;
    --sds-c-button-brand-color-border: white;    
    --sds-c-button-brand-text-color: purple;
    --sds-c-button-brand-text-color-hover: green;
