The Array.prototype.forEach () method lets each item of an array perform a given function once. -mdn
Suppose there was such a scene that you got such an array of
[{symbol: "XFX", price:240.22, volume:23432},{symbol: "TNZ", price:332.19, volume:234},{symbol: "Jxj", price:120.22, volume:5323},]
You need to create a new array for symbol, which is

Computer chassis, the normal is only the power supply, the motherboard (MB), the central Processing Unit (CPU), memory (RAM), graphics processor (GPU, commonly known as the graphics card), hard disk (HD) These things just. Usually appear the temperature is too high have: GPU,CPU, motherboard this 3 kind. (according to the probability of the occurrence of excessive temperature) because the GPU and CPU is the computer's largest power consumption of two hardware, the motherboard is because the powe
graphics card. In the case of graphics card, n card is best GTX750 and above, a card is best R9 370 and above, no matter which video card, can play most games on the market.
For the low-end graphics card, small series does not recommend the purchase of entry-level graphics card, so it does not make much sense, we know i3-6100 built-in core graphics, if you choose the entry level of the video card will waste resources.
Here I recommend a few good GTX750 graphics cards, can be suitabl
