如何在angular4中使用每个

Question

i have a doubt, i have 2 arrays

A=[2,2,3];

i create both array by pushing values .but when i use second array with foreach i didn't get values to display.

b.foreach((test,index)=>{
   console.log(test+"_0");
  }
)

i am using this format for extract values. is it is wrong ? need to change anything?

Answer 1

With angular and Typescript you need to use as,

for (let item of this.data) { 
    console.log(item +"_0");
}

Answer 2

forEach is always be in camelCase,

See this,

b.forEach((test,index) =>{
   console.log(test+"_"+index);
});
