To get current user id in Lightning Web Component, we need to import the "@salesforce/user/Id" Salesforce scoped module.
LWC.html
<template>
<div class="slds-text-heading_large slds-text-align_center">
User Id : {currentUserId}
</div>
</template>
LWC.js
import { LightningElement } from 'lwc';
import UserId from '@salesforce/user/Id';
export default class UserInformation extends LightningElement {
currentUserId = UserId;
}
Output:
LWCProgressIndicator.html
<template>
<div class="slds-theme_default">
<div class="slds-p-around_medium">
<lightning-progress-indicator type="path" current-step={selectedStep}>
<lightning-progress-step label="Step1" onstepfocus={selectStep1} value="Step1">

</lightning-progress-step>
<lightning-progress-step label="Step3" onstepfocus={selectStep3} value="Step3">
</lightning-progress-step>
<lightning-progress-step label="Step4" onstepfocus={selectStep4} value="Step4">
</lightning-progress-step>
</lightning-progress-indicator>
<div class="slds-m-vertical_medium">
<lightning-button label="Back" class="slds-m-left_x-small" onclick={handlePrev}></lightning-button>
<template if:false={isSelectStep4}>
<lightning-button variant="brand" class="slds-m-left_x-small" label="Next" onclick={handleNext}></lightning-button>
</template>
<template if:true={isSelectStep4}>
<lightning-button variant="brand" class="slds-m-left_x-small" label="Finish" onclick={handleFinish}></lightning-button>

import { LightningElement, track } from 'lwc';
export default class LWCProgressIndicator extends LightningElement {
@track selectedStep = 'Step1';
handleNext() {
var getselectedStep = this.selectedStep;
if(getselectedStep === 'Step1'){
this.selectedStep = 'Step2';

selectStep4() {

get isSelectStep4() {
return this.selectedStep === "Step4";
}
}
