TIPS 1: Easiest way of string to integer conversion.
const value_1 = "1"
const value_2 = "2"
function add(field_1, field_2){
return field_1 + field_2;
}
add(+value_1, +value_2);
TIPS 2: Easiest way of float to integer conversion.
const floatToInt = 23.9 | 0;
TIPS 3: Use Global object always should not need localStorage
Note[if data is is static then you should use it. and don’t use any kind secret or confidential data here..]
const user = {
first_name: "Rowan",
last_name: "Atkinson"
}
window.user=user
TIPS 3: Don’t use if not necessary ternary (?:)
const DemoComponent = ()=>{
const [show, setShow] = useState(false)
return (<div>
{show? <Message/>: ''}
</div>)
}
Right way with (&&)
const DemoComponent = ()=>{
const [show, setShow] = useState(false)
return (<div>
{show && <Message/>}
</div>)
}
TIPS 4: Don’t do it
if (variable1 !== null || variable1 !== undefined || variable1 !== '') {
let variable2 = variable1;
}
Do this short and simple
const variable2 = variable1 || 'new';
TIPS 5: Don’t do it
Math.floor(4.9) === 4 // true
Do this short and simple
~~4.9 === 4 // true
TIPS 6: Don’t do it
switch (something) {
case 1:
doSomething();
break;
case 2:
doSomethingElse();
break;
case 3:
doSomethingElseAndOver();
break;
// And so on...
}
Do this short and simple
const cases = {
1: doSomething,
2: doSomethingElse,
3: doSomethingElseAndOver
};
TIPS 7: Don’t do it
if(x == 1 || x == 5 || x == 7) {
console.log('X has some value');
}
Do this short and simple
([1,5,7].indexOf(x) !=- 1) && console.log('X has some value!');
TIPS 8: Don’t do it
const param1 =1;
const param2 = 2;
const param3 = 3;
const param4 = 4;
function MyFunc =(param1, param2, param3, param4)=>{
console.log(param1, param2, param3, param4)
}
MyFunc(param1, param2, param3, param4)
Do this short and simple
const params = {param1: 1, param2: 2, param3: 3, param4: 4}
function MyFunc =({param1, param2, param3, param4})=>{
console.log(param1, param2, param3, param4)
}
MyFunc(params)
TIPS 9: Don’t do it
function Myfunc(value){
if(value){
console.log("you have a value")
}else{
throw new Error("You don't have a value")
}
}
Do this short and simple
NOTE: If you check error first then it’s don’t go else block but if you do first one it will check first value is exist then if not found it will go the else block.
function Myfunc(value){
return !value ? throw new Error("You don't have a value") : console.log("you have a value")
}
